Question
The boys and girls in a college are in the ratio 3:2. If
15% of the boys and 25% of the girls are adults, then adults are approximately how much % less than the non-adults in the college?Solution
Let, the total number of boys and girls are 300 and 200 respectively. Total no. of students = 500 As per the question, Total no. of adult students = 15% of 300 + 25% of 200 = 45 +50=95 Total no. of non adult students = 500 - 95 = 405 ∴ Reqd. % = [(405 - 95)/405] × 100 = 76.54%
