Question

The cost of two articles are in the ratio 3 : 4, if there is 10% loss on the first article and the 20% gain on the second article. What is the overall percentage of loss or gain percent?​

Answer 1

Let price of 1st article be 3x

Price of Second article be 4x

Loss in 1st article = 3x x 10/100

= 3x/10

Gain in 2nd article = 4x x 20/100

= 4x/5

Total gain = 4x/5 - 3x/10

= 5x/10 = x/2

(As gain is more than loss)

Gain percentage = x/2 /x x 100

= 2/100 = 50%
