A: A and C can do 150,000 piece of work in 15 days each so 150,000 * 2 = 300,000. B can do 30% faster than A and C so he can do 3000 / 30 = 7500 piece of work in 15 days. So B can do 7500 x 30 = 26000 piece of work in 15 days. The total number of days required to finish 1,000,000 piece of work is 30000 * 16 = 46 days. The answer is (B).
