Question

In a school there are 1800 boys and 1200 girls. In an exam only 32 % of the boys passed and 50 % of the girls passed. Find the percentage of the total who did not pass.​

Answer 1

Explanation:

The total number of students is 1800 + 1200 = 3000

The % of boys who did not pass is 100% - 32% = 68%

The number of boys who did not pass is 68/100 * 1800 = 1224

The % of the girls who did not pass is 100% - 50% = 50%

The number of girls who did not pass was 50/100 * 1200 = 600

The total number who did not pass was 1824

The % who did not pass was 1824/3000 * 100 = 60.8%
