Question

if 20% of the student in a school are girls and the number of boys is 3016 then find the strength of the school​

Answer 1

Answer:

3770

Step-by-step explanation:

Let the total number of students be x

Number of girls = 20% of x = x * (20/100) = 0.2x

Number of boys = 3016

x = number of boys + number of girls

x = 3016 + 0.2x

⇒ x - 0.2 x = 3016

⇒ 0.8x = 3016

⇒ x = 3016/0.8

⇒x = 3770

So, the strength of the school is 3770.

Answer 2

Answer:

3770

Step-by-step explanation:

given:

20% is girls

strength of boys=100%-20%=80%

so,

80%of x=3016

80/100*x= 3016

80x= 301600

x=301600/80

x=3770

therefore the strength of school is 3770
