There are 100 boys and 900 girls in a school. 50% boys and 40% are present. The total number of students present are?
- 41%
- 44%
- 42%
- 43%
Explanation
Number of boys present: 50% of 100 = 0.5 x 100 = 50 boys
Number of girls present: 40% of 900 = 0.4 x 900 = 360 girls
Total students present = Boys present + Girls present
= 50 + 360
= 410
Now, let's find the percentage of students present:
Total students = Boys + Girls = 100 + 900 = 1000
Percentage of students present = (Total students present / Total students) x 100
= (410 / 1000) x 100
= 41%
