Correct Answer - Option 2 : 2
Given:
Working every day 8 hours 10 men can build 18 toys in 3 days
Concept Used:
If M1 man can do W1 work in D1 days by working daily T1 hours and M2 man can do W2 work in D2 days by working daily T2 hours then, M1 × W1 × D1 × T1 = M2 × W2 × D2 × T2
Calculation:
Here,
M1 = 10, W1 = 18, D1 = 3, T1 = 8
and M2 = 24, W2 = 15, T2 = 6
Let, D2 = x
Then,
M1 × W1 × D1 × T1 = M2 × W2 × D2 × T2
⇒ 10 × 18 × 3 × 8 = 24 × 15 × 6 × (x)
⇒ x = 2
∴ In 2 days, they can complete the work.
