Upper primary school mathematics question UPQ530
Sarin has 3286 stickers and Hairu has 2008 sticks. How many stickers must Sarin give to Hairu so that Hairu will have 178 more stickers than him?
Sarin has 3286 stickers and Hairu has 2008 stickers
Their differences in stickers = 3286 – 2008 = 1278
If they got to have equal number of stickers,
1278 ÷ 2 = 639
Since, Hairu have 178 more stickers than Sarin finally,
178 ÷ 2 = 89
The number of stickers Sarin to give to Hairu = 639 + 89 = 728
The total number of stickers = 3286 + 2008 = 5294
Finally, Hairu has 178 more stickers than Sarin,
From the model,
2 units = 5294 – 178 = 5116
1 unit = 2558
The number of stickers Sarin has finally = 2558
The number of stickers Sarin to give to Hairu = 3286 – 2558 = 728
