Question
50 children can decorate a hall in 25 days. If 25
children began decorating and after 10 days βzβ additional children joined, completing the decoration in 20 more days, find βzβ.Solution
Total work = 50 Γ 25 = 1250 units Work completed by 25 children in 10 days = 25 Γ 10 = 250 units Remaining work to be completed by (25 + z) children = 1250 β 250 = 1000 units Therefore, (25 + z) Γ 20 = 1000 Or, 25 + z = 1000 / 20 Or, 25 + z = 50 Or, z = 50 β 25 = 25 Number of children added = 25
