The average weight of students in group d cannot be determined

Solution:

Given, there are 60 students in a class.  

These students are divided into three groups a, b and c of 15, 20 and 25 students each.  

The groups a and c are combined to form group d.  

We need to find what is the average weight of the students in group d?

Here, we need average weight of each student to proceed further. But we are not given with sufficient data.

So, we have to choose the option data insufficient.

Hence, average weight of group D cannot be calculated due to in sufficient data.
