Question
12 engineers complete designing 180 blueprints in 15
days. If the goal is to complete 270 blueprints in 18 days, how many engineers are required?Solution
ATQ,
Let the required number of engineers be ‘w’ and let efficiency of each engineer be ‘M’ units per day
(12 × 15 × M) ÷ 180 = (18 × w × M) ÷ 270
So, w = 15
