Question

There are 60 students in class 7. The number of girls is one third the number of boys. Find the number of girls and boys in class 7.


​

Answer 1

Step-by-step explanation:

LET NO. OF BOYS BE X

NOW, NUMBER OF GIRLS = (1/3)X

.°. 60 = X + (1/3)X

.°. 60 = (4/3) X

.°. (60*3)/4 = X

.°. X = 45

.°. (1/4)X = 45 * 1/3

.°. no. of girls = 15

and no. of boys = 45
