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?

1. \(2\frac{18}{41}\)
2. 0
3. 5
4. \(4\frac{16}{21}\)

Answer 1

Correct Answer - Option 3 : 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
