- Inadequate Data

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (D)

**How to Solve**

**Step 1:**At First total weight of ( A + B + C ) = ( 55 X 3 ) = 165 kg and Total weight of ( B + D + E ) = ( 57 x 3 ) = 171 kg.

**Step 2:**Total weight of ( A + 2 B + C + D + E ) = ( 165 + 171 ) = 336 kg.

**Note: So, to find the average weight of A B C D and E, we need to know B’s weight. Which is not given here. So the data is inadequate.**

Example #3

There are two section X and Y of a college, consisting of 36 and 44 students respectively. If the average weight of section X is 40 Kg and that of section Y is 35 Kg. Find the average weight of the whole College?

**Step 2:**The total weight of both the section of the college is ( 36 x 40 + 44 x 35 ) = 2980

**So, Average weight of the whole college is = 2980 / 80 = 37.25 Kg.**
