To find :

The number of total students and boys

Solution :

Let the total students be as y

⇒ 60% of y = 18

⇒ 60/100 × y = 18

⇒ 60y = 18 × 100

⇒ 60y = 1800

⇒ y = 1800/60

⇒ y = 30

Total Students = 30 Students

$\rule{300}{1.5}$

Number of Boys =

⇒ 12

Boys = 12

$\therefore$ The total Students are 30 and boys are 12 in number.
