8 men can dig a pit in 20 days. if a man works half as much again a s a boy, then 4 men and 9 boys can dig a similar pit in:
divide(multiply(multiply(8, divide(const_3, const_2)), 20), add(multiply(4, divide(const_3, const_2)), 9))
explanation : 1 work done = 8 × 20 1 man = 3 / 2 boys 1 boy = 2 / 3 men then , 9 boys = 9 × 2 / 3 men = 6 men then , 4 men + 9 boys = 10 men then , 8 × 20 = 10 × ? days ? days = 8 × 20 / 10 = 16 days . answer : option d
