  I couldn't understand this -
  

  a city is 1/3 more than 1/2 high as
  higher temperature

  Ans#1:
  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).

  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.

  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?

  yea 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??

  its 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).

  my 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.
  Fuel is taken 1/4 more in going then coming. What is the fuel
  consumed in coming up?

  Divide 4.5 into 2 & 2.5. Now 0.5 is 25% of 2 . That should give you the answer.
  
  

  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?

  Sttepz did it the right way.
  
  

  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?

  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).
  
  Well, there can be better ways. That was my approach of guessing the answer in shortest time. Accuracy rate is around 80%.

  instead of that number divided by 3.what is the answer he actually
  has to get.

  😒 Please rewrite the question or give me the options.
  
  

  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.

  Assumption: The ships are moving towards each other 😀
  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
  with what height shadow C ft is

  The ratio is D:G . Assuming similar triangles (draw the figure yourself), the height with shadow C ft. should be DxC / G .

  Hi Neha,
  
  Here we go -
  

  1.From height of 8 mts on ball fell down and each time it bounces half the
  distnace back. so what will be the distance travelled ??

  Well, the series which comes to my mind is -
  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?
  a.49
  b.59
  c.both a and b---->Ans
  d.100

  49 = 13+17+19
  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.

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

  80? How?
  
  hey that was a great job, GOOD ADMIN
• 

  Neha

  i 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???

  the 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................
