Answer» Correct Answer - Option 5 : None of these Given: A’s profit percent = 20% B’s profit percent = 50% C’s profit percent = 30% D’s cost price = Rs.936 Calculation: Let, cost price for A = Rs.100x Cost price of B = {(100 + 20)/100} × 100x = Rs.120x Cost price of C = {(100 + 50)/100} × 120x = Rs.180x Cost price of D = {(100 + 30)/100} × 180x = Rs.234x = 936 ⇒ x = 4 Cost price of B = 120 × 4 = Rs.480 ∴ Cost price for B is Rs.480.
