Question

There are total 1250 students in a school. Out of 1250 students 560 are girls. Find out the total number of boys.

Answer 1

There are 690 boys in the school.

Step-by-step explanation:

Total number of students in the school, N = 1250.

The number of girls in the schools is, n (G) = 560.

Compute the number of boys as follows:

   $N = n (G) + n (B)$

$1250=560+n(B)$

$n (B)=1250+560\\n(B)=690$

Thus, there are 690 boys in the school.
