Question

6. If the sale price is increased by Rs. 80, a man makes a profit of 13% instead of 7% loss. Find the cost price.​

Answer 1

Answer:

CP=400

Step-by-step explanation:

Given,

let SP is'x'

if SP increased by Rs 80 man make a profit of 13% =(100+13)

x+80=113%                   (1)

if it sold for x rupees then there will be 7% loss means(100-7)

x=93%                          (2)

by dividing Eq(1) with Eq(2)

x+80/x=113/93

by solving we get x=372

if  93%=372

  100%=400 (CP)
