The bar graph given below shows the number of male teacher and female teachers in 5 schools.
K1 =The total number of male teachers in all 5 schools.
K2 = The total number of female teachers in all 5 schools.
What is the value of (K1 - K2)?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 160.
Total number of male teachers (K1) = 120 + 160 + 140 + 100 + 60 = 580
Total number of female teachers (K2) = 160 + 140 + 40 + 20 + 60 = 420
So, (K1 - K2) = 580 - 420 = 160
