Answer 2

Answer:

According to me....

Step-by-step explanation:

Total student = 60

ATQ,

9 girls ahead of Amal

means 7 boys are ahead of him

Girls are twice that of boys..

which mean

2x+x=60 (x=no.of boys)

3x=60

x=20

boys are 20 and

girls are 40

so....

20 - 7 = 13

(7 boys are ahead of him)

13 - 1 = 12

(1 is himself Amal)

So, 12 boys are after him in rank

(c)
