A Simple Question
Some Questions from TCS
Hi everyone
Can anyone answer the simple questions.These are the questions i found in last year TCS question papers.
1.A car is filled with four and half gallons of fuel for a round trip.
Fuel is taken 1/4 more in going then coming. What is the fuel
consumed in coming up?
2.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 tem. and highest temp.
is 100 degrees. Then what is the low temp?
3. A person, who decided to go to weekened 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?
a) 120 miles
b) between 120 and 140 miles
c) 160 miles

Nehaplz do write the solutions to the above questions.

JerryI couldn't understand this -
a city is 1/3 more than 1/2 high as
Ans#1:
higher temperature
Let 'x' be the fuel consumed during return journey. Then (5x/4) becomes the quantity of fuel required during the forward journey.
Therefore, x + (5x/4) = 4.5
=> x = 2 is the quantity of fuel consumed while coming up.
Ans#3:
Let 'x' be the time (in hours) for forward journey & 'y' be the time (in hours) for the return journey.
=> x+y =8
If (a) were right, then total distance travelled = 120 x 2 = 240 miles.
that means 40x + 30y = 240
Solving for x & y results in x = 0 which is invalid.
Similarly try for (c). Which results into y = 0 hours.
Therefore the correct answer is option (b).

p.s. post this question in Quantitative section. -
NehaAnswers
well Jerry, even i got my answer as 2 gallons for the first but the answer to the first question is 20 gallons.
i couldn't understand second question and answer to the third one is 120miles. -
rick
but the answer to the first question is 20 gallons.
How can it be 20 gallons? 😒
The car has only 4.5 gallons.
I couldn't get the answer to question 3. It has to be between 120 & 140 miles.
How did you get 120?
rick -
Nehayea u are rite rick the answer had to be 2gallons and the answer to third question should be (b) only.What about question 2 can anyone explain it??

sttepzits sooooo simple
2.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 tem. and highest temp.
is 100 degrees. Then what is the low temp?
Ans. wel d lower temp. is 40 n d higher's 60.
REASON : 40 is 1/3 more than 30 which is half of higher temp(60). -
Kaustubh Katdaremy way
I'll tell you how I did it. If you can do it that way, TCS won't be a problem 😀
1.A car is filled with four and half gallons of fuel for a round trip.
Divide 4.5 into 2 & 2.5. Now 0.5 is 25% of 2 . That should give you the answer.
Fuel is taken 1/4 more in going then coming. What is the fuel
consumed in coming up?
2.Low temperature at the night in a city is 1/3 more than 1/2 high as
Sttepz did it the right way.
higher temperature in a day. Sum of the low tem. and highest temp.
is 100 degrees. Then what is the low temp?
3. A person, who decided to go to weekened trip should not
If I had only 20 seconds to solve this; I'd divide 8 into 4 + 4. 40x4 + 30x4 = 160+120 = 280. Which is twice of the higher limit in option (b). I can be 90% sure that answer is (b).
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?
Well, there can be better ways. That was my approach of guessing the answer in shortest time.Accuracy rate is around 80%.

1.a sales person multiplied a number and get the answer is 3
instead of that number divided by 3.what is the answer he actually
has to get.
2.a ship started from a port and moving with I mph and another ship
started from L and moving with H mph.at which place these two ships
meet.
3.a building with height D ft shadow upto G.A neighbour building
with what height shadow C ft is -

😒 Please rewrite the question or give me the options.
instead of that number divided by 3.what is the answer he actually
has to get.
2.a ship started from a port and moving with I mph and another ship
Assumption: The ships are moving towards each other 😀
started from L and moving with H mph.at which place these two ships
meet.
Let' the ships meet after 't' hours. So,
t = { L / (I+H) } hrs.
Therefore, the ships meet at I x t miles from the port. Easy!
3.a building with height D ft shadow upto G.A neighbour building
The ratio is D:G . Assuming similar triangles (draw the figure yourself), the height with shadow C ft. should be DxC / G .
with what height shadow C ft is

Nehacan anybody give the solutions to 1st,3rd and 4th??
I got the answer to the 5th one as 80. -

Hi Neha,
Here we go -
1.From height of 8 mts on ball fell down and each time it bounces half the
Well, the series which comes to my mind is -
distnace back. so what will be the distance travelled ??
8 (initial) + 2 x 4 + 2 x 2 + 2 x 1 + ...... (infinite)
Which equals : 8 + 2 ( 4+2+1+..... )
= 8 + 2 [ 4 / ( 1-0.5 ) ] (Infinite Series Sum)
= 8 + 2 [ 4 x 2 ]
= 24
Option 'a'
3.which of the following is the sum of 3 consecutive prime nos?
49 = 13+17+19
a.49
b.59
c.both a and b---->Ans
d.100
59 = 17+19+23
Option 'c'
If 3 houses are to be painted,mr A can paint a house in 6 days mr B can do the same in 8 days...& mr.C in 12 days.if mr A does the work for 8 days & leaves for vacation, & mr B continues the work for the next 6 days, for how many days should mr.C work?
To complete the work,
A must work for 18 Days
B for 24 Days
C for 36 Days
Suppose that total work is of 72 units, then -
A does 4 units/day
B does 3 units/day
C does 2 unites/day
Now, for the first 8 days, A does 8 x 4 = 32 units
and for next 6 days, B does 6 x 3 = 18 units.
Therefore, total work completed by A & B is 32+18 = 50 units.
Remaining work, which is 72-50 = 22 units has to be completed by C. So with 2 units per day, he will complete the work in 22/2 = 11 Days.
Option 'a'.
Please verify.

NehaThanx!!...well how did u take the total work to be 72units in 4th question??
-
Kaustubh KatdareGuess?
18, 24 & 36
and ...
72 😀
umm... Guess? 😉

80? How?nehacan anybody give the solutions to 1st,3rd and 4th??
I got the answer to the 5th one as 80.
hey that was a great job, GOOD ADMIN -
Nehai got the answer to 5th one as 89
solution:
let the breads initially present to be x.
then,
(x/2+1/2) + [1/2(x/2+1/2)]+1/2 + [1/2{1/2(x/2+1/2)+1/2}]+1/2 +
1/2[1/2{1/2{x/2+1/2)+1/2}+1/2] + 3 = x
Solving the equation,
x = 89.
wat is the sum of infinite series??? -

), then the sum of the infinite geometric series
in whichis the first term and r is the common ratio is given by

Ronan Keatingthe 5 th one is 64..let there be X bread..the 1st one takes 1/2 bread and X/2 bread...so REMAINING bread is (X - 1/2 - X/2) =( X/2 - 1/2)
2nd one ....................remaining bread - 1/2(remaining bread)-1/2 (X/2 - 1/2) - 1/2 - (X/4 - 1/4) =(X/4 - 3/4)
3rd one ............................................................................... (X/4 - 3/4) - 1/2 - (X/8 - 3/8) =(X/8 - 7/8)
4th one ................................................................................ (X/8 - 7/8) -1/2 - (X/16 - 7/16) =(X/16 - 15/16)
SEE there is a sequence if there is N number of thief AND that is ( X / 2^N ) - ( (2^ N) -1) / ( 2^N)...............
So if you solve the 4th EQUATION (X/16 - 15 /16) = 3 ....You will see 64 is the ans..which is very close to the options..bt none of them................
