Question
If 60% of the students in a school are boys and the number girls 972, Find the number of boys are there in the school.
80%
70%
30%
20%
Hint:
First, we calculate total number of students by using the number of girls. Then, we use-- #Boys + #Girls = #Students to calculate the number of boys in the school.
The correct answer is: 30%
Step 1 of 2: Let’s say total number of Students in school is p. Now, given that 60% of the students in a school are boys. Therefore, (100-60)% = 40% of the students are girls. And given that the number of girls is 972. So, 40% of p = 972 → 0.4 × p = 972 → p = = 2430
Hence, total number of students is 2430. Step 2 of 2: #Boys + #Girls = #Students → #Boys = 2430 - 972 = 1458 Final Answer: The number of boys in the school is-- 1458.
