Correct Answer - Option 4 : None of these

**Calculation:**

Let the Mahesh number of apple is 2x.

The apple given to Suresh = x

The remaining apple on Mahesh after taking 1 apple from Suresh = x + 1

The apple given to Dinesh = (x + 1)/2

The remaining apple on Mahesh after taking 1 apple from Dinesh = (x + 1)/2 + 1

The apple given to Harish = 1/2[(x + 1)/2 + 1]

The remaining apple on Mahesh after taking 1 apple from Harish = 1/2[(x + 1)/2 + 1] + 1

According to the question;

⇒ 2x = 1/2[(x + 1)/2 + 1] + 1

⇒ 2x = (x + 1)/4 + 1/2 + 1

⇒ 2x = x/4 + 1/4 + 1/2 + 1

⇒ 2x - x/4 = 1/4 + 1/2 + 1

⇒ 7x/4 = 7/4

⇒ x = 1

The number of apple Mahesh has = 2 × 1 = 2

**∴ The number of apple Mahesh had in beginning is 2**
