Question : Kamal has some apples. He sold 40% more than he ate. If he sold 70 apples, how many did he eat?
Option 1: 18
Option 2: 42
Option 3: 50
Option 4: 90
Correct Answer: 50
Solution :
Let Kamal eat $y$ apples.
According to the question,
$y\times \frac{(100+40)}{100}=70$
⇒ $y\times \frac{140}{100}=70$
⇒ $y=50$
Hence, the correct answer is 50.
