Upper primary school mathematics question UPQ69

After a Congkak game, the number of marbles Sarin has is 6 more than 3 times that of Fatimah’s. The number of marbles that Hairu has is 3 more than 1/6 of Sarin’s. Hairu has 7 fewer marbles than Fatimah. How many marbles do Hairu have and how many do they have altogether?

Solutions:

Per the above model,

1 unit = 3 + 1 + 7 = 11

Total marbles = 9 × 11 + 3 +1 + 6 = 109

Sarin = 6 × 11 = 66 + 6 = 72

Fatimah = 2 × 11 = 22

Hairu = 12 + 3 = 15
