Let the number of boys be 7x & number of girls be 5x
Now,
Number of boys is 8 more than that of number of girls,
∴ A/q
∴ The Value of x ⟹ 4
Number of Boys ⟶ 7x ⟶ 7 × 4 ⟶ 28
Number of Girls ⟶ 5x ⟶ 5 × 4 ⟶ 20
∴ There are 28 boys & 20 girls
⟹ 20 + 28 = 48
∴ Total Strength of the Class is 48

Answer:
48
Step-by-step explanation:
Let the number of boys and girls be 7x and 5x respectively.
Acc. to the question,
=> 7x = 5x + 8
=> 7x - 5x = 8
=> 2x = 8
=> x = 8/2
=> x = 4
So, number of boys = 7x = 28
Number of girls = 5x = 20
Total students = 28 + 20 = 48
