Question

A man sells an article at a gain of 10%. If he had bought it at 10% less and sold it for 132 rupees, he would have still gained 10%. What is the cost price of the article ?​

Answer 1

Answer:

$\huge\underline\bold {Answer:}$

Let the C.P. (Cost Price) be x rupees.

Gain = 10%

S.P.(Selling Price) = 110x/100,

New C.P. = 90x/100

= 9x/10

New S.P. = 110% of 9x/10 rupees

= 99x/100, 11x/10 – 99x/100

= 132

=> 11x/100 = 132

$= > x = \frac{132 \times 100}{11} = 1200$

Hence cost price of the article is 1200 rupees.

Answer 2

Answer:

let C.P is 100. P = 10 % , S.P = 100 x 110 /100 = 110

new C .P = 100 -10 = 90 , P = 10 % , S.P = 90 x110/100 = 99

difference in S.P = 110 -99= 11

If difference is 11 , then C.P = 100

if difference is 132, then C.P = 100 x 132 /11 = 100 x 12 = Rs 1200
