Question
The average age of (x + 3) participants in a seminar is
18 years. If a 54-year-old organizer joins them, the average age rises by 1 year. Find x% of 400.Solution
ATQ,
Total age of participants = 18(x + 3) years According to the condition, 18(x+3)+54=(18+1)(x+3+1) 18x + 54 + 54 = 19x + 76 108 = x + 76 x = 32 So, 32% of 400 = 128
