A farmer bought a goat for Rs 15000 and a cow for Rs 35000. If he sold the goat at 10% profit and cow at 20% loss, find his profit or loss percent in whole transaction. ​

Sagot :

He sold the goat at 2 10% profit so he sold the goat for:  15,000 x 1.10 = 16,500

He sold the cow for a loss, so he sold the cow for 35000 x 0.80 = 28,000

Total he paid for both: 15,000 + 35,000 = 50,000

Total he sold both for: 16,500 + 28,000 = 44,500

He sold them for less than what he paid so he lost money.

Subtract sold amount from bought amount:

50,000 - 44,500 = 5,500

Divide the difference by the amount he paid:

5,500 / 50,000 =  0.11 x 100 = 11%

His loss percentage was 11%
