Question

In a music school, 70% students are boys. If the total girls are 255 then find out the number of boys?
1. 595
2. 850
3. 540
4. 575

Answer 1

Correct Answer - Option 1 : 595

Given:

Percentage of boys = 70%

Total number of girls = 255

Calculation:

Percentage of girls = (100 – 70)%

⇒ 30%

According to the question,

⇒ 30% = 255

⇒ 70% = (255/30%) × 70%

⇒ 595

∴ The number of boys is 595
