Question

23. Prasanth bought a car and paid 10% less
than the original price. He sold it with
30% profit on the price he had paid.
What percentage of profit did he earn on
the original price?​

Answer 1

Let actual cost of car was 100

SP for Prashant =100−10% of 100

= 100 − 10/100 × 100 = 90

SP for Vartika =90 + 30% of 90

= 90 + 30/100 × 90 = 90+ 27 = 117

Gain = 117 − 90 = 27

Gain % on actual cost price

= 17/100 × 100 = 17%.
