Question

A has some mangoes. He sold 40% more than he ate. If he sold 70 mangoes, how many did he eat?

Options

• 50

• 90

• 18

• 42

Answer 1

50
Explanation :
Let he ate x mangoes.
Then, sold mangoes = x + 40% of x
But given sold mangoes = 70
∴ x + 40% of x = 70

⇒    x + `40/100`x = 70

⇒  `(14x)/10`= 70

⇒   x = 70` xx10/14` = 50

Hence, we ate 50 mangoes.
