Correct Answer - Option 2 : 56.5

**Given:**

Mahesh’s opinion = weight is greater than 55 kg but less than 62 kg

His brother’s opinion = weight is greater than 50 kg but less than 60 kg

His mother’s opinion = weight is less than 58 kg

**Calculations:**

Let Mahesh’s weight be x kg.

According to Mahesh his age is 55 < x < 62

According to Mahesh’s brother 50 < x < 60

According to Mahesh’s mother x < 58

⇒ From above three statements 55 < x < 58

⇒ Probable weights are either 56 kg or 57 kg

Required Average = (56 + 57)/2

⇒ 113/2

⇒ 56.5 kg

**The average of different probable weights of Mahesh is 56.5 kg.**
