Question

Rahul bought a pen for Rs 15. For how much should he sell it to gain 40%?​

Answer 1

Answer:

Rs. 21

Step-by-step explanation:

Given:

C.P of the pen = 15

Profit % = 15%

We know that,

Profit % = (Profit/C.P) × 100

=> 15 = (Profit/40) × 100

=> 15/100 = Profit/40

=> (3/20) × 40 = Profit

=> 6 = Profit

Now,

For profit, S.P > C.P

We Know that,

Profit = S.P – C.P

=> 6 = S.P – 15

=> 6 + 15 = S.P

=> S.P = 21

Hence, Rahul should sell the pen for rupees 21 so as to gain a profit of 40%.
