Step-by-step explanation:
The number of boys and girls are in ratio 7:5. The number of boys is 8 more than the number of girls. Find the strength of the class?
ANSWER
______________________________
Boys : Girls = 7 : 5
Let the no. of Boys be 7x and No. of girls be 5x
It is given that there are 8 more boys than girls
This means that
7x - 5x = 8
2x = 8
x = 4
___________________________
No. of Boys = 4 × 7
No. of Boys = 28
No. of Girls = 4 × 5
No. of Girls = 20
Total Students = 28 + 20
Total Students = 48
