Question

11. By selling a chair for + 420 a dealer suffered a loss of 16%, At what price should he sell it to gain 20%?​

Answer 1

Answer:

Rs 600

Step-by-step explanation:

let cost price of chair be x

loss = 16% of C.P

= 16% of x

= 16x/100

= 4x/25  

Sales price = Cost Price - loss

420 = x - (4x/25)

420 =  (25x - 4x) / 25

(420 × 25)/21 = x

x = 500

Cost price of chair = 500

To calculate sales price for gain of 20%

Sales Price = Cost Price + 20% of cost Price

                  = 500 + (20/100) × 500

                  = 500 + 100 = 600

Hence to make gain of 20% , dealer should sell it for Rs 600.
