The cost price of an article A is Rs.160 and selling price of another article B is Rs.288. If the selling price of A will be equal to the cost price of B, then the profit after selling an article A is 20%. What is the profit percentage on article B?
Answer & Explanation
Answer : Option B |

Cost price of an article A = Rs.160
Selling price of A = 160 $\times$ $120 \over 100$ = Rs. 192
According to the question,
Cost price of B = Rs.192
Selling price of B = Rs.288
Profit = 288 - 192 = Rs.96
Required Profit percentage = $96\over192$ $\times$ 100 = 50 % |
