The bar graph given below shows the number of boys (B) and girls (G) in 5 given schools.
R = Total number of boys in the given 5 schools.
T = Average number of girls in the given 5 schools.
What is the value of R - T?
Show answer & explanation
Correct answer: B
Explanation
Given:
Boys (B) = 100, 120, 180, 60, 140
Girls (G) = 80, 160, 100, 120, 200
According to the formula:
R = Total number of boys
T = Average number of girls
R = 100 + 120 + 180 + 60 + 140 = 600
Total number of girls = 80 + 160 + 100 + 120 + 200 = 660
T = 660 / 5 = 132
R − T = 600 − 132 = 468
