Question

1. Rakesh can do a piece of work in 20 days. How much work can he do in 4 days?


2. Rohan can paint 1/3 of a painting in 6 days. How many days will he take to complete painting?​

Answer 1

Step-by-step explanation:

1) = Time taken by Rakesh to do a piece of work is 20

= days Work done by Rakesh in 1 day = 1/20 Work done

= by Rakesh in 4 days = 4 × 1/20 = 1/5

∴ 1/5th work can be done by Rakesh in 4days.

2) let the painting be x

$\frac{1}{3} \times x \: = 6$

$x = 18 \: days$
