Answer 1

Answer:

C. 120

Given:

There are total 200 students in a school, of which $\frac{2}{5}$ th are boys.

Formula Used:

total students = no. of boys + no. of girls

Calculation:

Let the number of girls in the school be 'x'

$⇒ 200 = 200\times{\frac{2}{5}} + x$

⇒ x = 200 - 80

⇒ x = 120

∴ Required number of girls in the school = 120
