Answer & Solution
Correct Answer:
Option
D
Total weight of (36 + 44) Students, = (36 × 40 + 44 × 35) kg
= 2980 kg Therefore average weight of the whole class, = $$ {\frac{{2980}}{{80}}} $$ kg. Therefore average weight = 37.25 kg.
= 2980 kg Therefore average weight of the whole class, = $$ {\frac{{2980}}{{80}}} $$ kg. Therefore average weight = 37.25 kg.
