The cost price of an article 'A' is Rs. 160 and selling price of another article 'B' is Rs. 240. If the selling price of A will be equal to the cost price of B, then the profit after selling A is 20% on B, we get profit of 48 Rs. is

(A) 16.66%
(B) 20% profit
(C) 25% profit
(D) 8 1/3% loss

(C) 25% profit

Let the cost price of article B be C.

Selling price of A = Cost price of B = C
Therefore, selling price of A = C = Rs. 240

Profit after selling A is 20% on B = (20/100) * C = 0.2C = Rs. 48

Therefore, C = Rs. 240

Profit percentage = (Selling price - Cost price) / Cost price * 100
Profit percentage = (240 - 160) / 160 * 100 = 80 / 160 * 100 = 50%

Profit percentage on selling A = (240 - 160) / 160 * 100 = 50%

Therefore, the profit after selling A is 25%.
