Shop keeper's Selling price SP = (100+ profit% )/100 * Cost Price = Rs 840

cost price = Rs 840 * 100 / 120 = Rs 700

Cost price of 2nd transistor = Rs 700 + Rs 25 = Rs 725

Profit = same as that for the first transistor = 20%

Selling price = (100 + profit% )/100 *Cost price = 120/100 * 725

= Rs 870

cost price = Rs 840 * 100 / 120 = Rs 700

Cost price of 2nd transistor = Rs 700 + Rs 25 = Rs 725

Profit = same as that for the first transistor = 20%

Selling price = (100 + profit% )/100 *Cost price = 120/100 * 725

= Rs 870
