D. \frac{1}{4}

Solution:    1 day work of Somya = \frac{1}{50}

Therefore, in 20 days she can do 20 × \frac{1}{50} = \frac{20}{50} = (\frac{2}{5})^{th} part of the work.

Correct option: C

Type 2: Tips and Tricks and Shortcuts for Work and Time to  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.


A. 2.5 %

B. -2 %

C. 1.2 %

D. 2.5 %

Solution:     Positive efficiency = 5%

Negative efficiency = 2.5%

Therefore the Net efficiency = (5 – 2.5) = 2.5%

Correct option: A

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?


A. 50 days

B. 10 days

C. 60 days

D. 45 days

Solution:     Karan’s 1 day work = \frac{1}{50}.

Work done by Karan in 15 days = 15 × \frac{1}{50} = \frac{3}{10}

Therefore, remaining work = 1 – \frac{3}{10} = \frac{7}{10}

Tarun finishes this remaining \frac{7}{10} work in 35 days.

Therefore, Tarun can finish the work in \frac{35}{\frac{7}{10}} = 50

Correct option: A

Question 1. Hetal’s one day work is \frac{1}{20} and Avnika’s one day work is \frac{1}{30}  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?


A. Rs. 833.33

B. Rs. 800

C. Rs.235

D. Rs. 338.3

Solution:     Hetal’s total work done = \frac{10}{20} = \frac{1}{2}

Avnika’s total work = \frac{10}{30} = \frac{1}{3}

The work together completed in \frac{1}{2} + \frac{1}{3} = \frac{5}{6}

Remaining work = 1 – \frac{5}{6} = \frac{1}{6}

Therefore, Yasha’s share = 5000 × \frac{1}{6} = \frac{5000}{6} = Rs 833.33

Correct option:  A
