By what percent is the total number of boys in Arts stream more than the total number of boys in Science stream in the years 2012 to 2020?
Answer & explanation
Correct answer: option 1
Total number of boys in arts stream from 2012 to 2020 = 48 + 42 + 45 + 39 + 36 = 210
Total number of boys in science stream = 40 + 42 + 38 + 41 + 39 = 200
Required percentage = \(\frac{210 - 200}{200}\) × 100
= \(\frac{10}{200}\) × 100
= 5%
