A: A and C can finish 100,000 piece of work in 15 days each so they can finish 100,000 * 2 = 200,000 piece of work in 15 days. B can do 30% faster than A and C so he can do 200,000 /.3 = 60,000 piece of work in 15 days. Combined they can finish 100,000 + 200,000 + 60,000 = 400,000 piece of work in 15 days. To finish million piece of work they will take 400,000 / 15 = 46 days. The answer is (B).
