Answer 1

Here,

A/c to question

The total no of boys and girls in a clas is 48 so, B+G=48......1

2nd case :

No of girls is 8 more than boys

so, B=G+8.....2

NOW FROM EQN 1

B=48-G...3

AGAIN

PUTIING THE VALUE OF B IN EQN 3

B=48-G

G+8=48-G

G+G=48-8

2G=40

G=20

THE NO OF GIRLS=20

SO,

B=G+8

B=20+8

=28.
