Answer:
48 students
Step-by-step explanation:
Given that the number of boys and girls in class are in ratio 7:5.
Let's say the number of boys be 7a and girls be 5a.
Also, said that the number of boys is 8 more than the number of girls.
→ 7a = 5a + 8
→ 7a - 5a = 8
→ 2a = 8
Divide by 2 on both sides,
→ 2a/2 = 8/2
→ a = 4
Hence, the numbers of boys in the class are 7(4) = 28 and number of girls in the class are 5(4) = 20.
We need to find the total strength of the class.
Total strength of the class = Number of boys + Number of girls
= 28 + 20
= 48
Hence, the strength of the class is 48 students.
