Graph shows number of students in a college in five years.
Total number of students = boys students + girls students
The percentage of girls students who are using Scooty are 40%, 35%, 55%, 60% and 70% in five years respectively then approximately the number of girls students who are using Scooty is what percent more than the number of girls students who are not using Scooty?
Explanation:
Total number of girls students who are using Scooty in five years = 800 × 40/100 + 1100 × 35/100 + 2000 × 55/100 + 2400 × 60/100 + 2200 × 70/100
= 320 + 385 + 1100 + 1440 + 1540= 4785
Total number of girls students in college in five years = 800 + 1100 + 2000 + 2400 + 2200 = 8500
Total number of Girls students who are not using Scooty = 8500 – 4785 = 3715
⇒ 4785 = 3715 + 3715 × ? /100
⇒ ? = 28.80% ≈ 29%
