Question
A group of 30 students has an average score of 60 in an
exam. If 5 more students join the group and their average score is 70, find the new average score of the entire group.Solution
Total score of 30 students = 30 × 60 = 1800. Total score of 5 new students = 5 × 70 = 350. Total score of 35 students = 1800 + 350 = 2150. New average score = 2150 / 35 = 61.43. Answer: a) 61.4
