If 45 men can build a wall of 360 m length in 18 days, how many men will take 15 days to build a similar type of wall of length 180 m?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 27 men.
(M1 × T1)/W1 = (M2 × T2)/W2
⇒ (45 × 18)/360 = (M2 × 15)/180
⇒ M2 = (45 × 9)/15 = 27 men
