At first
Number of guests= 420
Number of adults= 420 x 0.6 = 252
Number of Children= 420 - 252 (adults) = 168
Children Girls= (1/8) of the children = 1/8 x 168 = 21
Children Boys= 168 -21= 147
After some boys left
Adults were 70% already (still 252 adults); let Z be the new number of guests after some boys left
New number of guests =(252/Z) x (0.7) = 360
So number of boys that left= 420-360= 60
A. 60 boys left
So from the original number of boys (147) minus the number of boys who left (60) equals 87
87- 21 (number of girls) = 66
B. There are 66 more boys than girls
I wish I could but maths is my enemy
A. 10%?
B. 15%
