# Solutions for Time and Work Practice Test

Friends, here are the solutions for our Time and Work Practice Test. Before checking these solutions, Please take the test from here and try to solve the questions on your own. All the Best.

1.
Let the number of answer papers examined be X in the first case, then the number of answer papers examined in the second case will be 2X.

P1 = 4   H1 = 5   D1 = 10    W1 = X
P2 = 2   H2 = ?   D2 = 20     W2 = 2X

But (P1. H1. D1)/(W1) = (P2. H2. D2)/(W2)

=> (4 . 5 . 10) / (X) = (2. H2. 20) / (2X)

=>  H2 = (200 . 2X) / (X . 40)  = 10

2.
P1 = 7   D1 = 12   W1 = 1
P2 = ?   D2 = 8      W2 = 2

(P1. D1) / (W1) = (P2. D2) / (W2)

=>   (7 . 12) /1 = (P2 . 8)/2

=> P2 = (7 . 12) / 4 = 21

3.
3 women = 2 men

=> 21 women = 14 men

P1 = 15    H1 = 8   D1 = 21
P2 = 14    H2 = 6   D2 = ?

But P1. H1. D1 = P2. H2. D2

15 . 8 . 21 = 14 . 6 . D2

=>  D2 = (15 . 8 . 21) / (14 . 6)  = 30

4.
P1 = 25   D1 = 24
P2 = ?     D2 = 10

P1. D1 = P2. D2

25 . 24 = P2 . 10

=>  P2 = (25 . 24) / 10 = 60

5.
Six men leave after six days. So the work  which is to be done by 12 men in 6 days must be done by 6 men only

P1 = 12   D1 = 6
P2 = 6     D2 = ?

=>   12 . 6 = 6 . D2

=>  D2 = 12

6.
Builder employs 150 men for first 20 days and 150 + 80 = 230 men for the remaining 50 - 20 = 30 days to complete the work in stipulated time.

If additional 80 men are not employed then the work which is done by 230 men in 30 days should be done by 150 men only. i.e.,

P1 = 230    D1 = 30
P2 = 150    D2 = ?

=> 230 . 30 = 150 . D2

=> D2 = (230 . 30) / 150   = 46

The schedule will be extended by 46 - 30 = 16 days

7.
Two men or three women can do the work in same time

=> 2M = 3W

=> 1M + 1W = (3W/2) + 1W  = 5W/2

P1 = 3           D1 = 4
P2 = 5/2        D2 = ?

=>   (3  .  4) = (5/2) . D2

=> D2  = (12 . 2) / 5 = 24/5

8.
One man or three women or five boys can do a piece of work in same time

=>  1M  =  3W = 5B

=> 1M = 5B and 3W = 5B

=> 1M + 1W + 1B    =   5B + (5B/3) + 1B = 23B/3

Now consider the boys strength to solve the problem

P1 = 5    D1 = 46
P2 = 23/3    D2 = ?

=>  5 . 46 = (23/2) . D2

=> D2 = (5 . 46 . 3) / 23 = 30

9.
8 men can do the work in 20 days and 8 women in 32 days

=> 8M . 20 = 8W . 32

=> 20M = 32W => 5M = 8W

=> 5M + 8W = 8W + 8W = 16W

Now consider the women strength to solve the problem

P1 = 8   D1 = 32
P2 = 16   D2 = ?

=>  8 . 32 = 16 . D2

=> D2 = (8 . 32) / 16  = 16

10.
2M . 6 = 2W . 9 = 3C . 8
=> 12 M = 18 W = 24 C

12M = 18W      12M = 24C
=> 2M = 3W     => 1M = 2C

But 3W+4C = 2M+2M = 4M

If X be the number of men required to finish the remaining work in 1 day

2 . 6 = 4 . 1 + X . 1

=> X = 12 - 4  = 8

11.
X's one day work = 1/24

=> Y is twice as fast as X

Y's one day work = 2 . (1/24) = 1/12

(X + Y)'s one day work =   (1/24) + (1/12)  = (1+2)/24  = 1/8

X and Y together can do the work in 8 days

Shortcut Method
By applying the formula (4) discussed in our previous post

x = 24   k = 2

So X and Y together can do the work in x/(k+1) = 24/(2+1) = 8 days

12.
Yesterday time taken by Vani to finish the work = 300/15 = 20

Today she is 40% faster i.e., 140% as efficient as the other day

Today time taken by her to finish the work = 20/140% = (20 . 100) / 140 = 14 min

The required difference = 20 - 14 = 6 mins

Shortcut Method
Applying the same formula

x = 300/15 = 20
k = (100 + 40)% = 140/100 = 1.4

So today Vani can finish the work in 20/1.4 which is approximately equals to  14 days

Required difference = 20 - 14 = 6 min

1. Hello Mam

How are you

I want to ask some question today I took the exam sbi
associate and done well with the help of your notes and daily content provided
by your website. After completing the test I started descriptive paper and I
did one minor but big mistake. I marked 4 ans on computer but done all five
question on sheet but forget to mark 5th question. i am quite sure
that I can clear this exam but know I am worried about descriptive part because
I forget to mark green on computer

My question is that whether
sbi consider my descriptive part
or failed me because I cant able to mark 5th question of descriptive
because they mentioned that all 5 question are necessary to answer to clear
descriptive paper.Please tell me I am worried a lot for this

Thanks
