Henry Park Pri Sch 2007 PSLE Math Prelim Q40

There were 30 more members in the IT Club than in the Art Club. 15 members left the Art Club for the IT Club. It was then found that the number of members in the IT Club was 5 times as many as the number of members in the Art Club. How many members were there in both clubs altogether?


4 units ----- 60
1 unit ----- 60 divided by 4 = 15
(Altogether) 6 units ----- 15 x 6 = 90

Answer: There were 90 members altogether.
