1. Rs. 23,920
2. Rs. 23,228
3. Rs. 23,862
4. Rs. 23,958

Answer 1

Correct Answer - Option 4 : Rs. 23,958

Given:

Initial Profit = 10%

Initial SP = 21,780

Formula used:

Profit% = Profit/CP × 100

Calculation:

Suppose the cost price of laptop is Rs. x.

Therefore, 110% of x = 21,780

⇒ x = Rs. 19800

∴ CP = Rs. 19,800

According to question –

New Selling price when profit is 21% = 121% of 19,800

⇒ Rs. 23,958
