Correct Answer 5

Calculation:

Total number of boys in Arts stream = 48 + 42 + 45 + 39 + 36 = 210

Total number of boys in Science stream = 40 + 42 + 38 + 41 + 39 = 200

Required percentage = (210 - 200)/200 × 100 = 5%

∴ total number of boys in Arts stream is 5% more than the total number of boys in Science stream in the years 2012 to 2020
