72 % of the students in a school are boys. If the number of girls in the school is 140, then the number of boys in the school is:

400

360

320

280

✅ Correct Option: 2

Girls form $100 - 72 = 28\%$ of the school. So $0.28 \times \text{total} = 140$ , giving a total of $500$ students. Boys $= 72\%$ of $500 = 360$ .
