a) Women = 144
% of women = 144/360 x 100% = 40%
b) Boy is 3w
Men = 4w
Girls= w
Total = 8w
8w = 360-144
8w= 216
w = 27
c) Girl = 27 degrees —> 81
Therefore all 360 degrees = 360/27 x 81 = 1080.
d) i) For participating only parents, a boy and a girls.
Maximum group can form = 81
Therefore, maximum from this group are = 81 x 4
= 324
ii) Fraction = 324/1080
= 3/10.
Hope this helps
