Answer:

60

Step-by-step explanation:

Let the total number of boys in class = x

A/S,

20x/100=12

2x/10=12

2x=120

x=60

Answer 2

Answer: 60

Step-by-step explanation:

$\Large \bf Given-:$

• Total no. of boys in the class = 12

• Rest are girls

• Total no. of boys constitutes 20% of the strength of the class.

$\Large \bf To\: Find:-$

Total number of students in the class

$\Large \bf Solution:-$

Let 'x' be the total no. of students in the class.

No. of boys = 12

Now, total no. of boys constitutes 20% of x . (Given)

$\implies \frac{20}{100}\times x = 12\\\\\\\implies x = \frac{12\times 100}{20} \\\\\\\implies \bf x = 60$

No. of girls = 60-12 = 48

Hence, there are 60 students in the class out of which 12 are boys and 48 are girls.
