Quantitative Comparison Practice Test 4

Solutions (6−7):
Let the number of boys = x
Number of the girls = 65 −x
Share of all the boys = 80x
Share of all the girls = 30 (65 −x)
According to the statement,
80x + 30 (65 − x) = 3,900
80x + 1,950 − 30x = 3,900
50x = 3,900 − 1,950
50x = 1,950
x = 39
Number of boys = x = 39 boys
Number of girls = 65 − x = 65 − 39 = 26 girls
6. So, Column A is equal to Column B.
