The average weight of 8 student was 48 if the average weight of first 5 students is 45, then the average weight for the remaining student is?
Answer & explanation
Correct answer: option 2
Weight of 8 students = 48 × 8 = 384
Weight of 5 students = 45 × 5 = 225
Weight of remaining 3 students = 384 - 225 = 159
Average weight of 3 students = \(\frac{159}{3}\) = 53
