Question

what should be percentage gain on a product when it is sold for Rs 120 with a gain of rs 20​

Answer 1

SP of a product = Rs. 120

Since the transaction is gain SP > CP

Gain = SP - CP

Rs. 20 = 120 - CP

CP = 120 - 20

CP = 100

CP of a product = Rs. 100

Gain % = Gain/CP * 100

= 20/100 * 100

= 20%

Therefore the gain % on a product is 20%.

Answer 2

Given:

The selling price of the product = Rs. 120

Gain = Rs. 20

To find:

The percentage of gain.

Solution:

Let us first find the cost price:

CP = SP - Gain

CP = 120 - 20

CP = Rs. 100

Thus, the gain percentage will be:

= 20/100 * 100

= 20%

Thus, the gain percentage will be 20%.
