Should be relatively straightforward.
10% of the poulation are children and 40% are adults 18-65. 5% of those adults, so 2% of the population, go with childreen so 8% of population are children which go with OAPs, so 80% of the children go with OAPs.

5% of adults take a child. There are 40% adults in the population, so 5% of that is 2% of the population. So 1 in 5 children is accompanied by an adult, so 4 in 5 children (80%) are accompanied by an oap.

Ahhh thank you, how did you know that you aren't supposed to use the 120,000 to help answer the question and just the percentages? And is 1/5 from 2/10 (2% of adults and 10% of children in total)?

Some of the questions will give more info than required. Youve got to decide what you need to solve a problem, not just rely on the question elf to give it to you precisely. You could work it out in terms of absolute numbers (try it?) but its not necessary.

I tried doing it with 120,000 because that method makes more logical sense to me but I couldn't work it out but thank you so much!
