Question : 4 of 40

Marks: +1, -0

Solution:

Average weight of 40 students = 36.2 kg

Total weight = 36.2 × 40 = 1,448 kg

Sum of weight of three students = 42.3 + 39.7 + 39.5 = 121.5 kg

Sum of weight of 43 students = 1,448 + 121.5 = 1,569.5 kg

Average weight of 43 students

=\frac{1569.5}{43}

= 36.5 kg
