Correct Answer

Explanation

The average of the different possible weights of Varun is 67 kg.
To find this, we can use the following steps:
Let Varun's weight be X kg.
According to Varun, 65 < According to Varun's father, 60 < X < 70.
According to Varun's sister, X <= 68.
The different possible weights of Varun, or the values that satisfy all of these conditions, are 66, 67, and 68.
The average of these weights is (66 + 67 + 68) / 3 = 201 / 3 = 67 kg.
