Question

The selling price of a chair is Rs 980 with a loss of 20%. What is the cost price of the chair?

Answer 1

1225

Explanation:

a loss of 20% represents 80% ( 100 - 20) of the cost price

100% represents the cost price

To find the cost price divide the selling price by 80 to find 1% and multiply by 100 to find cost price

cost price =
`(980)/(80)` × 100 = 1225
