Here, (6 men + 8 boys) × 10 = (26 men + 48 boys) × 2 ⇒ 60 men + 80 boys = 52 men + 96 boys ⇒ 8 men = 16 boys. Hence, 1 man = 2 boys. Then, 6 men + 8 boys = 12 boys + 8 boys = 20 boys and 15 men + 20 boys = 30 boys + 20 boys = 50 boys Now, 50 boys' 1 day's work = 50 ×

20×10

Hence, 15 men and 20 boys will do the same work in 4 days.
