Question

In a school. 0.8 part of the strength of the school is boys and the number of girls is 150. Find the number boys in the school​

Answer 1

Answer:

Let the total students be x

According to the question

0.8x+150=x

(4x/5)+150=x

150=x-4x/5

150=(5x-4x)/5

150=x/5

x=150*5

So, total students=750

Total boys=0.8*750

=(4/5)*750

=600

So, total boys=600
