Question

Solve It .......................​

Answer 1

Answer:

1 = 115/5= 23

Then girls = 23×3= 69

Answer 2

GIVEN:-

RATIO OF BOYS AND GIRLS are 5 : 3

No. of boys is 115

FIND:-

NO. OF GIRLS?

SOLUTION:-

No. of boys is = 300

Let, no. of girls be x

ACCORDING TO QUESTION

$=> \frac{no. \: of \: boys}{no. \: of \: girls} = \frac{5}{3}$

$=>\frac{300}{x} = \frac{5}{3}$

cross MULTIPLY it,

$=>5x = 300 \times 3$

$=>x = \frac{300 \times 3}{5}$

$=>x = \frac{ \cancel{ 900}}{ \cancel{ 5} } = 180$

$=>x = 180$

$hence, \: no. \: of \: girls \boxed{180}$
