**Ques - 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%. What is the profit on 'B'? **

**(a) 16.66%**

**(b) 50%**

**(c) 25%**

**(d) none of these **

**Solution - **

CP of article 'A' = 160

SP of article 'B' = x

Profit of A = 20%

Profit of A = 1/5

Here,

CP = 5, SP = 6

160 = 5

1 = 160/5

1 = 32

SP = 6

SP = 6 × 32

**SP of A = 192**

If the selling price of 'A' will be equal to the cost price of B,

**CP of B = 192**

**SP of B = 240**

Profit = SP - CP

= 240 - 192

= 48

Profit % = (48/192) × 100

**= 25%**

Therefore,

**The profit of B is 25%.**

Hence,

The correct answer is option **(c) 25%.**
