2) A box of 150 packets consists of 1kg packets and 2kg packets. Total
weight of box
is
264kg. How many 2kg packets are
there?
Sol: Given x= 2 kg Packs
y= 1 kg packs
=> x + y = 150 .......... Eqn 1
=> 2x + y = 264 .......... Eqn 2
On solving these two equations
x = 114
By using equation 1
114 + y = 150
=> y = 36
=>Number
of 2 kg Packs = 114.

9) The size of the bucket is N kb.
The bucket fills at the rate of 0.1 kb per millisecond. A programmer sends a
program to receiver. There it waits for 10 milliseconds. And response will be
back to programmer in 20 milliseconds. How much time the program takes to get a
response back to the programmer, after it is sent?
Sol:
The time being
taken to fill the bucket.
After reaching program it waits there for 10ms and back to the programmer in
20 ms.
then total time to get the response is
20ms +10 ms=30ms
Ans:
30ms

size of the bucket is 10 kilobytes. Eh bucket gets filled at the rate of 0.0001
kilobytes per millisecond. The transmission time from sender to receiver is 10
milliseconds per bucket. After the receipt of the bucket the receiver sends an
acknowledgement that reaches sender in 100 milliseconds. Assuming no error
during transmission, write a formula to calculate the time taken in
seconds to successfully complete the transfer of a file of size N kilobytes.
Ans: (n/1000)*(n/10)*10+ (n/100).... (Not 100% sure)
11)A fisherman's day is rated as good if he catches 9 fishes ,fair if 7
fishes and bad if 5 fishes .He catches 53 fishes in a week n had all good, fair
n bad days in the week. So how many good, fair n bad days did the fisher man
had in the week.
Sol:
good days means --- 9 fishes so 53/9=4(remainder=17)
if u assume 5 then there is no chance for bad days.
fair days means ----- 7 fishes so remaining 17 ---
17/7=1(remainder=10) if u assume 2 then there is no chance for bad days.
bad days means -------5 fishes so remaining
10---10/5=2days.
4*9=36
7*1=7
2*5=10
36+7+10=53...
Ans:
4 good, 1 fair, 2bad. ==== total 7 days.
12) x+y+z=7--------- eq1
9*x+7*y+5*z=53 -------eq2
Sol:
Multiply
eq 1 by 9,
9*x+9*y+9*z=35
-------------eq3
From
eq2 and eq3
2*y+4*z=10-----eq4
Since
all x, y and z are integer i should put a integer value of y such that z sud be
integer in eq 4.....And there will be two value y=1 or 3 then z = 2 or 1 from
eq 4
For
first y=1,z=2 then from eq1 x= 4
So
9*4+1*7+2*5=53.... Satisfied
Now
for second y=3 z=1 then from eq1 x=3
So
9*3+3*7+1*5=53 ......satisfied
So
finally there are two solution of this question
Ans:(x,y,z)=(4,1,2)
and (3,3,1)...
13) Y catches 5 times more fishes than X. If total number of fishes
caught by X and Y is 42, then number of fishes caught by X?
Sol: let no. of fish x catches=p
No. caught by y =r
r=5p.
Given r+p=42
Then p=7, r=35
14) Three companies are working independently and receiving the savings
20%, 30%, 40%. If the companies work combine, what will be their net savings?
Sol: Suppose total income
is 100
So
amount x is getting is 80
y is 70
z =60
Total=210
But
total money is 300
300-210=90
So
they are getting 90 rs less
90 is
30% of 300 so they r getting 30% discount
15) The ratio of incomes of C and D is 3:4.the ratio of their
expenditures is 4:5.Find the ratio of their savings if the savings of C is one
fourths of his income?

51) The total expense of a boarding house is partly fixed and partly
variable with the number of boarders. The charge is Rs.70 per head when there
are 25 boarders and Rs.60 when there are 50 boarders. Find the charge per head
when there are 100 boarders.
a) 65
b) 55
c) 50
d) 45
Sol: let a = fixed cost and
k =
variable cost and n = number of boarders
Total
cost when 25 boarders c = 25*70 = 1750 i.e. 1750 = a + 25k
Total
cost when 50 boarders c = 50*60 = 3000 i.e. 3000 = a + 50k
Solving
above 2 eqns, 3000-1750 = 25k i.e. 1250 = 25k i.e. k = 50
Therefore,
substituting this value of k in either of above 2 eqns we get
a =
500 (a = 3000-50*50 = 500 or a = 1750 - 25*50 = 500)
So
total cost when 100 boarders = c = a + 100k = 500 + 100*50 = 5500
So
cost per head = 5500/100 = 55
52) Amal bought 5 pens, 7 pencils and 4 erasers. Rajan bought 6 pens, 8
erasers and 14 pencils for an amount which was half more than what Amal had
paid. What % of the total amount paid by Amal was paid for pens?
a) 37.5%
b) 62.5%
c) 50%
d) None of these
Sol: Let, 5 pens + 7 pencils + 4 erasers = x rupees
So 10
pens + 14 pencils + 8 erasers = 2*x rupees
Also
mentioned, 6 pens + 14 pencils + 8 erasers = 1.5*x rupees
So
(10-6) = 4 pens = (2-1.5) x rupees
So 4
pens = 0.5x rupees => 8 pens = x rupees
So 5
pens = 5x/8 rupees = 5/8 of total (note x rupees is total amt paid by
Amal)
i.e. 5/8 = 500/8% = 62.5%
Ans: 62.5%
53) I lost Rs.68 in two races. My second race loss is Rs.6 more than the
first race. My friend lost Rs.4 more than me in the second race. What is the

2x +
6 = 68
2x =
68-6
2x =
62
x=31
x is
the amt lost in I race
x+ 6
= 31+6=37 is lost in second race
Then
my friend lost 37 + 4 = 41 Rs
Ans: 41 Rs

meets the cart in the middle after half an hour. He takes the mail and returns
back, by doing so, he saves twenty minutes. How early did the plane arrive? Sol: Assume he started at 1:00, so at 1:30 he met cart .He returned
home at 2:00.so it took him 1 hour for the total journey. By doing this he
saved 20 min. So the actual time if the plane is not late is 1 hour and 20 min.
So the actual time of plane is at 1:40.The cart traveled a time of 10 min
before it met him. So the plane is 10 min early.
Ans: 10 min 80) Ram singh goes to his office in the city every day from his suburban
house. His driver Mangaram drops him at the railway station in the morning and
picks him up in the evening. Every evening Ram singh reaches the station at 5
o'clock. Mangaram also reaches at the same time. One day Ram singh started
early from his office and came to the station at 4 o'clock. Not wanting to wait

up on the way and takes him back house, half an hour early. How much time did
Ram singh walked? 81) 2 trees are there. One grows at 3/5 of the other. In 4 years total
growth of the trees is 8 ft. what growth will smaller tree have in 2 years. Sol: THE BIG TREE GROWS 8FT IN 4 YEARS=>THE BIG TREE GROWS 4FT IN
2 YEARS.WHEN WE DIVIDE 4FT/5=.8*3=>2.4
4 (x+ (3/5) x)
=88x/5=2x=5/4
After 2 years x= (3/5)*(5/4)*2 =1.5 (less than 2 feet) 82) There is a six digit code. Its first two digits, multiplied by 3
gives all ones. And the next two digits multiplied by 6 give all twos.
Remaining two digits multiplied by 9 gives all threes. Then what is the code? Sol: Assume the digit xx xx xx (six
digits) First
Two digit xx * 3=111
xx
=111/3=37 (First
two digits of 1 is not divisible by 3 so we can use 111) Second
Two digit xx*6=222
xx=222/6=37 (First
two digits of 2 is not divisible by 6 so we can use 222) Third
Two digit xx*9=333
xx=333/9=37 (First
two digits of 3 is not divisible by 9 so we can use 333) 83) There are 4 balls and 4 boxes of colors yellow, pink, red and green.
Red ball is in a box whose color is same as that of the ball in a yellow box.
Red box has green ball. In which box you find the yellow ball? Sol: Yellow box can have either of pink/yellow balls. if we put a yellow ball in "yellow" box then it
would imply that "yellow" is also the color of the box which has the
red ball(because according 2 d question,d box of the red ball n the ball in the
yellow box have same color) Thus this possibility is ruled out... Therefore the ball in yellow box must be pink, hence the
color of box contain in red ball is also pink.... =>the box color left out is "green", which is
allotted to the only box left, the one which has yellow ball.
Ans: green 84) A bag contains 20 yellow balls, 10 green balls, 5 white balls, 8
black balls, and 1 red ball. How many minimum balls one should pick out so that
to make sure the he gets at least 2 balls of same color. Sol: suppose he picks 5 balls of all different colors then when he
picks up the sixth one, it must match any on of the previously drawn ball
color. Thus he must pick 6 balls
Ans: he should pick 6 balls totally. 85) WHAT IS THE NUMBER OF ZEROS AT THE END OF THE PRODUCT OF THE NUMBERS
FROM 1 TO 100? Sol: For every 5 in unit place one zero is added so between 1 to 100 there are 10 nos like 5,15,25,..,95
which has 5 in unit place. Similarly for every no divisible by 10 one zero is added
in the answer so between 1 to 100 , 11 zeros are added For 25, 50,
75 3 extra zeros are added So total no of zeros are 10+11+3=24 86) There are two numbers in the ratio 8:9. If the smaller of the two
numbers is increased by 12 and the larger number is reduced by 19 thee the
ratio of the two numbers is 5:9. Find the larger number? Sol: 8x: 9x initially 8x+ 12: 9x - 19
= 5x: 9x 8x+12 =
5x -> x = 4 9x = 36
(NOT SURE ABOUT THE ANSWER) 87) There are three different boxes A, B and C. Difference between
weights of A and B is 3 kgs. And between B and C is 5 kgs. Then what is the
maximum sum of the differences of all possible combinations when two boxes are
taken each time Sol: A-B = 3 B-c = 5 A-c =
8 so sum of diff = 8+3+5
= 16 kgs 88) A and B are shooters and having their exam. A and B fall short of 10
and 2 shots respectively to the qualifying mark. If each of them fired at least
one shot and even by adding their total score together, they fall short of the
qualifying mark, what is the qualifying mark? Sol: Because each had at least 1 shot done so 10 + 1 = 11 And 9 + 2 = 11 So the
ans is 11 89) A, B, C, and D tells the following times by looking at their watches.
A tells it is 3 to 12. B tells it is 3 past 12 . C tells it is 12:2. D tells it
is half a dozen too soon to 12. No two watches show the same time. The
difference between the watches is 2,3,4,5 respectively. Whose watch shows
maximum time? Sol: A shows 11:57, B shows 12:03, C shows 12:02
and D shows 11:06 therefore,
Max time is for B 90) Falling height is proportional to square of the time. One object
falls 64cm in 2sec than in 6sec from how much height the object will fall. Sol: The falling height is proportional
to the square of the time. Now,
the falling height is 64cm at 2sec So, the
proportional constant is=64/ (2*2) =16; So,
at 6sec the object fall maximum (16*6*6) cm=576cm; Now,
the object may be situated at any where. If it
is>576 only that time the object falling 576cm within 6sec
.Otherwise if it is situated<576 then it fall only that height at
6sec. 91) Last
