Question

at a fitness center the numberof male increases by 20% to 96 and the number of female decreases by 30% to 84 find the overall increases or decreases in total members

Answer 1

1.2M = 96

M = 96/1.2 = 80 = original number of males

.7F = 84

F = 84/.7 = 120 = original number of females

original total number of members = 120 + 80 = 200

new total number of members = 84 +96 = 180

200 to 180 is a decrease of 20

20 is 10% of 200

the total membership decreased by 10%
