Answer 1

Heya !!!

This is Your answer.

It is given that two cows are sold at a price of Rs. 300% each.
On one it gains 20% profit and on the other, there is a loss of 20%.

we have to find his gain/loss percent in whole....

Usually.... I write long answers with full explanation but here I will take shortcut......

In case where where gain and loss percentages are common on same selling price, there always incurs a loss in total.
To calculate that loss percentage, there is a formula...

Loss on total deal% = (common gain/loss%/10)^2

= > Final Loss % = (20/10)^2 = 400/100 = 4%.

Hence, there is a loss of 4% on total deal.

Hope it helps.....
