Question
15 boys can finish a task in 8 days while 3 men can
finish the same task in 4 days. In how many days can 2 boys and 3 men together finish the task?Solution
15B × 8 = 3M × 4 where B = boys and M = men Or, 1M = 15B × 8 / 3 × 4 = 10B Therefore, 2B + 3M = 2B + 3 × 10B = 2B + 30B = 32B Therefore, 32 boys can finish the work in 8 days.
