A computer seller gained 20% by selling a computer for Rs 24000.
i. What was its cost price?
ii. If he had to gain 30%, at what price should have he sold it?​



Answer :

Answer:

1 - 20000

2 - 26000

Step-by-step explanation:

Lets say the cost price is 100x, so the selling price would be 120x

120x = 24000

x = 200

the cost price was 100x so 20000,

a 30% gain would be to sell at 130x so 26000
