Hi Chetanaites
Do the all the qstins given below.. u will get 80% common from these... all of we got... TCS always repeat same qstins...Just do these first..... It is proved by everyone that.. these qstins are repeated in each year...
QUANTITATIVE APTITUDE SECTION
1. Two pencils costs 8 cents, then 5 pencils cost how much
Sol: 2 pencils è 8 cents => 1 pencil > 4 cents
Therefore 5 pencils cost = 5 * 4 = 20 cents
2. A work is done by two people in 24 min. one of them can do this work a lonely in 40 min. how much time required to do the same work for the second person.
Sol: (A+B) can do the work in = 1/24 min.
A alone can do the same work in = 1/40 min.
B alone can do the same work in = (A+B)'s  A's = 1/24  1/40 = 1/60
Therefore, b can do the same work in = 60 min
3. A car is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallon more in going than coming. What is the fuel consumed in coming up?
Sol Before the trip, car is filled with = 4 ½ gallon of oil
Let 'X' be the quantity of fuel consumed for the trip in one direction
The fuel consumed while going = X + ¼
The fuel consumed while coming = X
Therefore, the fuel consumed for the trip = (X + ¼) + X = 4 ½
=> 2X + ¼ = 4 ½ => 2X = 4 ½  ¼ => 2X = 4 ¼ => X= 2. approx
Therefore the fuel consumed while coming = 2 gallon
4. Low temperature at the night in a city is 1/3 more than 1/2 high as higher temperature in a day. Sum of the low temperature and highest temp. is 100 degrees. Then what is the low temp?
Sol: 40 deg.
5. A person, who decided to go to weekend trip should not exceed 8 hours driving in a day. Average speed of forward journey is 40 m/h. Due to traffic in Sundays, the return journey average speed is 30 m/h. How far he can select a picnic spot?

Divided by 3
Answer: 1/3.
7. A ship started from port and moving with I miles per hour and another ship started from L and moving with H miles per hour. At which place these two ships meet?

9. A person was fined for exceeding the speed limit by 10mph. Another person was also fined for exceeding the same speed limit by twice the same. If the second person was traveling at a speed of 35 mph, find the speed limit.
Sol: Let 'x' be the speed limit
Person 'A' was fined for exceeding the speed limit by = 10mph
Person 'B' was fined for exceeding the speed limit by = twice of 'A'
= 2*10mph=20mph
given that the second person was traveling at the speed of 35mph => 35mph  20mph = 15mph
Therefore the speed limit is =15 mph

Do the all the qstins given below.. u will get 80% common from these... all of we got... TCS always repeat same qstins...Just do these first..... It is proved by everyone that.. these qstins are repeated in each year...
QUANTITATIVE APTITUDE SECTION
1. Two pencils costs 8 cents, then 5 pencils cost how much
Sol: 2 pencils è 8 cents => 1 pencil > 4 cents
Therefore 5 pencils cost = 5 * 4 = 20 cents
2. A work is done by two people in 24 min. one of them can do this work a lonely in 40 min. how much time required to do the same work for the second person.
Sol: (A+B) can do the work in = 1/24 min.
A alone can do the same work in = 1/40 min.
B alone can do the same work in = (A+B)'s  A's = 1/24  1/40 = 1/60
Therefore, b can do the same work in = 60 min
3. A car is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallon more in going than coming. What is the fuel consumed in coming up?
Sol Before the trip, car is filled with = 4 ½ gallon of oil
Let 'X' be the quantity of fuel consumed for the trip in one direction
The fuel consumed while going = X + ¼
The fuel consumed while coming = X
Therefore, the fuel consumed for the trip = (X + ¼) + X = 4 ½
=> 2X + ¼ = 4 ½ => 2X = 4 ½  ¼ => 2X = 4 ¼ => X= 2. approx
Therefore the fuel consumed while coming = 2 gallon
