Lets say there were x xompetitors and y non competitors
So total noumber of people = x+y
No . coupons for competitors = 3x
No. of coupons for non-competitors = 2y
So total number of coupons = 2y+3x
Now go ahead
Hope someone can help with this problem:
On a sports day of a school, each competitor was given 3 drink coupons while each non-competitor was given 2 drink coupons. The ratio of the numnber of pupils to the number of coupons given was 6:17. What fraction of the pupils in the school competed in the sports day?
Appreciate if you can show detail workings.
