Question

Three men paint a house in 20 days. How many days do 30 men take to do the same?

• A. 3 days
• B. 2 days
• C. 60 days
• D. 12 days

Answer 1

Answer: (B)

2 days

Using $Work=men\times days$ we can see that

$Work=3\times 20=60$

Since the work is same

$60=30\times days$

$days=2$

Therefore, Answer is $\left(B\right)$
