Number of students enrolled in different branches of higher secondary of five schools.

Number of students enrolled in science branch of school A is what percentage of total number of students of all the five school from all branches?

8

Number of students enrolled in science in school A = 60

Total number of students of all the five school from all branches

= ( 60+70+50 ) + ( 78+82+40 ) + ( 45+40+35 ) + ( 40+45+40 ) + ( 40+35+50 )

= 180 + 200 + 120 + 125 + 125

= 750

Percentage of number of students in science in school A to total number of students of all the five school from all branches

= \(\frac{60 }{750}\) × 100

= \(\frac{4 }{50}\) × 100

= 8%
