We need to find the value of (J1 ∶ J2), where:
J1 is the total number of male and female teachers in school P.
J2 is the difference between the total number of male and the total number of female teachers in all 5 schools.
J1 = Total number of male and female teachers in school P
J1 = Sum of Male + Sum of Female
J1 = 80 + 60 = 140
J1 = 140
J2 = Difference between the total number of male and the total number of female teachers in all the 5 schools
J2 = Sum of Male - Sum of Female
J2 =(60 + 80 + 70 + 50 + 30) - (80 + 70 + 20 + 10 + 30)
J2 = 290 - 210
J2 = 80
140 ∶ 80.
7 : 4
Therefore, the value of (J1 ∶ J2) is 7 : 4
