Question
A group of 8 men or 10 women can complete a certain
task in 21 days. How many days will it take for a combination of 10 women and 4 men to complete the same task?Solution
It is given, 8 men = 10 women (based on their efficiency) 10 women + 4 men = 10 women + 4 × (10/8) women = (10 + 5) women = 15 women So, w1 × t1 = w2 × t2 10 × 21 = 15 × t2 t2 = 14 days.
