Question

On selling a stool for ₹8,378, the value of gain is 20% more than the value of loss incurred on selling it for ₹1,756. In order to gain 50%, find the selling price (in ₹).​

A.

7,150

B.

7,148

C.

7,151

D.

7,149

Correct option is D

Given:

Selling Price 1 SP1 = ₹8378 (with gain)

Selling Price 2 SP2 = ₹1756 (with loss)

Gain = 20% more than loss

Required gain = 50%

Solution:

Let Cost Price = x

According to the question; 

8378 − x = 120100\frac{120}{100}​(x − 1756) 

8378 - x = 1.2x - 2107.2

8378 + 2107.2 = 1.2x + x

10485.2 = 2.2x

x = 10485.22.2\frac{10485.2}{2.2}​ = 4766

To gain 50%,

SP = x + 0.5x = 1.5x = 1.5×47661.5 \times 4766​ = ₹7149
