Question

11. An article is sold at a gain of 20%.Had it been sold for Rs 125 more, the gain
would be 25%. Find its cost price.​

Answer 1

Answer:

CP = Rs. 2500

Step-by-step explanation:

Let CP = 100 X

If gain is 20% , SP = 120 X

If Sold for 125 more. ie. 120X + 125 gain will be 25 %

$\frac{(120x + 125) - 100x}{100x} = \frac{25}{100}$

X = 25

CP = Rs. 2500

(or)

let CP = 100X

In 20 % gain, SP = 120 X

In 25 % gain, SP = 125 X

Change in SP, 5X = Rs. 125

Then, X = 25.

CP = Rs. 2500
