Question

A man sold a product at 30% profit if cost price &selling price are rs.100 & rs.170 less respectively.the profit percentage will be 25%.find the cost price initially

Answer 1

Answer:

Cost price = rs.900

Step-by-step explanation:

Let initial cost price be x , then selling price = 1.3x

Cost price  rs. 100 less = x-100

Selling price rs. 170 less = 1.3x - 170

So 1.25(x-100) = 1.3x - 170

1.25x - 125 = 1.3x - 170

0.05x = 45

x = 45/0.05 = 900

Cost price = rs.900 Selling price = rs.1170

Cost price  rs. 100 less = rs.800

Selling price rs. 170 less = rs.1000

Profit percentage = (1000-800)/800= 0.25 = 25%
