Time and Work Problems For IBPS Exam 2017

Correct Answers 

  1. Option B.

15M = 23W  = 36B

SO, M­­­­­­1 * D1 * T1 *W1  = M2 * D2 * T2 * W2

15*12*8*9/4  =  ( 10+X)  *30*6  =  8

 

  1. Option A.

According to the question-  X/ 8  +  (X-1)/16  + (X-2)/24 = 1

    X = 5 Days.

  1. Option B.

Work di-one by  A and B in 6 days = 6 × [ 1/20  +1/15] = 7/10

Remaining work  =  1- 7/10 = 3/10

If C is able to do  the work  in X days , then

4/20  +  4/X  = 3/10  = 40 days

  1. Option D.

Work done by A in 1 hr =  work done by  A and C in 1 hr  – work done by B and C in 1 hr =

3/8  –  ¼   = 1/8

So, work done by A and C in 1 hr = 1/8  +1/6  = 7/24

Hence,  A and B  complete a piece of work in  24/7  days.

  1. Option D.

 Work done by  (P+Q+R) = 1 ………….(i)

Work done by  (P+Q) = 19/23 ………….(ii)

Work done by  (Q+R) = 8/23 ………….(iii)

FROM  (ii)  + (iii)  – (i)  =  Q = 19/23 +8/23  – 1 = 4/23

Work of Q = 4/23  ×5750  = 1000

  1. Option A.

 Part  of the cistern  filled  in 2hr by pipe A =  2/3

Part  of the cistern  filled  in 1hr by pipe B =  ¼

Total part filled up =  2/3  + ¼  = 11/12

When all pipe open  together = 1/3 +1/4 – 1  = – 5/12

So, time take to empty  11/12 part  = 11/12  × 12/5  =11/5 hr =  2hr 12 min

Req. time  5 + 2:12 = 7:12 pm

 

  1. Option D.

According to the question = work by both  = √4×16  = √64 = 8 days

  1. Option C.

According to the question =  250 *20*50 =            M2 * 10*10  = M2  = 250

  1. Option A.

( 2M + 5 W ) ×  12 =  (5M +2W) × 9

2W = 1M

2M+5W = 9W =  9 × 12 = 3 ×D2 = 36 days.

  1. Option B.

 P1   20                    9

                   180 

P2   30                    6

                               15

Time take to fill 1/3 rd  tank  = 180 /3× 5 =  4 Hr

After,  this actual  work  done by  ( P1 +P2)  =  (15) –  1/3 (15)

Time taken  for  fill  remaining  tank = 180 – 60 /10           =  12 hr

Total time Req.  for fill the tank =  4+12 = 16 Hr
