Answer:
Step-by-step explanation:
1. Since 3% where late, students punctual where 100 - 3 = 97%.
Total students = 1500
Thus number of punctual students = 97% of 1500 = 97/100 * 1500 = 1455.
2. Percentage of children = 100% - ( 35.5 + 40) = 100% - 75.5% = 24.5%.
Total people attended = 1800.
So number of children = 24.5% of 1800 = 24.5/100 * 1800 = 441.
