Question

the cost of an article increases by rs 100 the selling price increases by the new profit decreases from 15% to 10% what is the original cost price

Answer 1

hoi mate here's your answer

Let original CP = x

Original profit = 15%

Original SP = 1.15x

New cost price = x + 100

New Selling Price = 1.15x * 1.1 = 1.265 x

New profit = 0.10(x + 100)

NSP - NCP = NP

1.265x - x - 100 = 0.10(x + 100)

0.265x - 0.10x = 100 + 10

0.165x = 110

x = 666.67
