The number of students playing football in college B is approximately what percentage more than the number of students playing badminton in college C?
The number of students playing football in college B = 40 The number of students playing badminton in college C = 15 × (70/30) = 35 Required % = [(40 – 35)/35] × 100 = 14% approx.
