Question
If one child has half the work efficiency of an adult,
determine the duration required for 8 children to construct a wall, which is 60% as large as the one built by 12 adults in 15 days.Solution
Let the efficiency of each man be '2x' units/day So, total work = 2x X 12 X 15 = '360x' units And efficiency of a child = 2x ÷ 2 = 'x' units/day So, required time = (360x X 0.6) ÷ (8 X x) = 27 days Hence, option a.
