School |
Total number of students [ Boys + Girls] |
Total number of girls |
The number of boys |
|
A |
320 |
180 |
320 – 180 = 140 |
|
B |
280 |
160 |
120 |
|
C |
360 |
200 |
160 |
|
D |
380 |
210 |
170 |
|
E |
420 |
200 |
220 |
Calculation
Total boys in all schools (A to E) =
140 + 120 + 160 + 170 + 220 = 810
Total schools = 5
Average boys = [810/5] = 162
⇒ m= 162/5 = 32.4,
So, m = 32.4
