If 12 men can build a wall 60 metres long in 5 days, then what length of a similar wall can be built by 24 men in 2 days ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 48 metres.
We know that,
(M1 × D1 × H1)/W1 = (M2 × D2 × H2)/W2
⇒ (12 × 5)/60 = (24 × 2)/W2
⇒ 1 = 48/W2
⇒ W2 = 48 metres
Thus, the length of the wall will be 48 meters
