Nanyang Pri Sch 2009 P6 CA1 Math Paper 2 Q3

The ratio of the number of Chloe's stickers to the number of Faith's stickers is 3:5. The ratio of the number of Faith's stickers to Melissa's stickers is 6:7. If Melissa has 204 stickers more than Chloe, how many stickers do they have altogether?

Solution

Melissa - Chloe --> 204

35 units - 18 units --> 204

17 units --> 204

1 unit --> 204 divided by 17 = 12

All stickers

Chloe + Faith + Melissa

18 + 30 + 35 = 83

83 units --> 83 x 12 = 996

Answer: 996 stickers
