At an exhibition, 30% of those present were boys. 5/14 of the remainder were girls and the rest were adults. There were 45 more adults than boys. How many more children than adults were there at the exhibition?
Boys ----- 30%
Girls ----- 5/14 of remainder
= 5/14 x 70% = 25%
Total children ----- 30% (boys) + 25% (girls) = 55%
Adults ----- 100% - 55% (children) = 45%
There were 45 more adults than boys, therefore,
45% (adults) – 30% (boys) ----- 45 people
15% ----- 45 people
1% ----- (45 people) divided by 15 = 3 people
Children more than adults -----
55% (total children) – 45% (adults) = 10%
10% ----- (3 people) x 10 = 30 people
Answer: There were 30 more adults than children.
