Answer» GIVEN Cost Price of 1st book = Rs.450. Profit % on SELLING 1st book = 20% Selling price of 1st book = {(100 + Profit%) / 100} * C.P = {(100 + 20) / 100} * 450 = (120 / 100) * 450 = 12 * 45 = 540 Rs. Cost price of 2nd book = Rs.540 Loss % on selling 2nd book = 5% Selling price of 2nd book = {(100 - Loss%) / 100} * C.P = {(100 - 5) / 100} * 540 = (95 / 100) * 540 = 513 Rs. OVERALL profit = Selling price of 2nd book - Cost Price of 1st book = Rs.513 - Rs.450 = Rs. 63. Given Cost Price of 1st book = Rs.450. Profit % on selling 1st book = 20% Selling price of 1st book = {(100 + Profit%) / 100} * C.P = {(100 + 20) / 100} * 450 = (120 / 100) * 450 = 12 * 45 = 540 Rs. Cost price of 2nd book = Rs.540 Loss % on selling 2nd book = 5% Selling price of 2nd book = {(100 - Loss%) / 100} * C.P = {(100 - 5) / 100} * 540 = (95 / 100) * 540 = 513 Rs. Overall profit = Selling price of 2nd book - Cost Price of 1st book = Rs.513 - Rs.450 = Rs. 63.

Answer»

Cost Price of 1st book = Rs.450.

Profit % on SELLING 1st book = 20%

Selling price of 1st book = {(100 + Profit%) / 100} * C.P

= {(100 + 20) / 100} * 450

= (120 / 100) * 450

= 12 * 45

= 540 Rs.

Cost price of 2nd book = Rs.540

Loss % on selling 2nd book = 5%

Selling price of 2nd book = {(100 - Loss%) / 100} * C.P

= {(100 - 5) / 100} * 540

= (95 / 100) * 540

= 513 Rs.

OVERALL profit = Selling price of 2nd book - Cost Price of 1st book

= Rs.513 - Rs.450

= Rs. 63.
