Question

There were 24 boys and 20 girls in a chess club last year. This year the number or boys increased by 25% but the number of girls decreased by 10%. Was there an increase or decrease in overall membership?

Answer 1

There was an increase in the overall membership

Answer 2

original=24+20=44
ok so find increase and decrease
25%=1/4
10%=1/10

24 TIMES 1/4=6
increase by 25%
24+6=30

girls decrease by 1/10
20 times 1/10=2
20-2=18

38+18=48
48>44
increase
