Options:
A. 1/5
B.3/8
C.2/5
D.1/4

Solution: 1 day work of Somya = 1/50
Therefore, in 20 days she can do 20 × 1/50 = 20/50 = 2/5th part of the work

## Type 2: Calculate time/work when efficiency is given in percentage

### Question 1.

Positive efficiency of a Neha is 5%. Negative efficiency of Shreya is 2.5%. Find out the net efficiency.

Options:
A. 2.5 %
B. -2 %
C. 1.2 %
D.-2.5 %

Correct option: A
Solution:
Positive efficiency = 5%
Negative efficiency = 2.5%
Therefore the Net efficiency = (5 – 2.5) = 2.5%

## Type 3: Calculate time/work when workers leave in between

### Question 1.

Karan can do a piece of work in 50 days. He works for 15 days and then leaves. Tarun comes and finishes the remaining work in 35 days. In how many days Tarun alone can finish the work?

Options:
A. 50 days
B. 10 days
C. 60 days
D. 45 days

Correct option: A
Solution: Karan’s 1 day work = 1/50.
Work done by Karan in 15 days = 15 * 1/ 50  = 3/10
Therefore, remaining work = 1 – 3/10 = 7/10
Tarun finishes this remaining 7/10 work in 35 days.
Therefore, Tarun can finish the work in 35/7/10 = 50

### Question 1.

Hetal’s one day work is 1/20 and Avnika’s one day work is 1/30 days but with the help of Yasha they finished the work in 10 days. For that work they got total of Rs. 5000. Find the share of Yasha?

Options:
A. Rs. 833.33
B. Rs. 800
C. Rs.235
D. Rs. 338.3

Correct option:  A
Solution: Hetal’s total work done = 10/20 = 1/2
Avnika’s total work = 10/30 = 1/3
The work together completed in ½ + 1/3 = 5/6
Remaining work = 1 – 5/6 = 1/6
Therefore, Yasha’s share = 5000*1/6 = 5000/6 = Rs 833.33
