A bag of stickers was distributed equally among 15 girls. When 7 of these girls gave up
47 of their share, the rest of the girls received 7 more stickers each. How many stickers were there in the bag?

| Number |

8 |
15 |
| Value |
4 u |
7 |
7 u |
| Total value |
28 u |
56 |
105 u |
Number of girls who received the extra stickers
= 15 - 7
= 8
Total number of extra stickers received by the rest of the girls
= 8 x 7
= 56
Total number of stickers given up
= 7 x 4 u
= 28 u
28 u = 56
1 u = 56 ÷ 28 = 2
Total number of stickers for 15 girls
= 15 x 7 u
= 105 u
= 105 x 2
= 210
Answer: 210
