Question

By selling a speaker for RS 768 ,a man loss 20%.In order to gain 20% how much should he sell a speaker

Answer 1

Answer: Rs 1152

Step-by-step explanation:

Let the cost price of the speaker be X.

According to the question

X- 20% of X = 768.

X- X/5 = 768

(5X- X)/5 = 768

4X= 768*5

4X= 3840

X = 3840/4

X= 960

Therefore the cost of the speaker is Rs 960/-

In order to make a gain of 20% he need to sell the product at

Rs 960+ 20% of 960

960+20/100 of 960

960+1/5 of 960

960+192

1152

The person should sell at Rs 1152/- to make a gain of 20%.

Hope this helps.
