s.p=12×115÷100=13.80

Answer 2

Calculation of Selling price based on Profit and Cost price

The Selling price of the pen would be Rs. 13.80 to obtain a 15% profit

Step-by-step explanation:

Let the cost price of the pen be Rs. x.

The profit noted in Case 1 = 10% of CP, i.e., 10/100 x

The SP of the pen = 13.20

The CP of the pen is calculated as:

SP = CP + Profit

X + 10/100 x = 13.20

110/100 x = 13.20

X = 1320/ 110

Thus, x = 12

The Cost price of the pen is Rs 12.

If he wanted to acquire a profit of 15%, the selling price of the pen would be calculated as:

SP = CP + P

    = 12 + (15 x 12)/100

    = 12 + 180/100

SP = 13.80

Thus, the Selling price of the pen would be Rs. 13.80 to obtain a 15% profit
