25 of their share, the rest of the girls received 9 more stickers each. How many stickers were there in the bag?

8 |
17 |
| Value |
2 u |
9 |
5 u |
| Total value |
18 u |
72 |
85 u |
Number of girls who received the extra stickers
= 17 - 9
= 8
Total number of extra stickers received by the rest of the girls
= 8 x 9
= 72
Total number of stickers given up
= 9 x 2 u
= 18 u
18 u = 72
1 u = 72 ÷ 18 = 4
Total number of stickers for 17 girls
= 17 x 5 u
= 85 u
= 85 x 4
= 340
Answer: 340
