710 of their share, the rest of the girls received 12 more stickers each. How many stickers were there in the bag?

| Value |
7 u |
12 |
10 u |
| Total value |
42 u |
84 |
130 u |
Number of girls who received the extra stickers
= 13 - 6
= 7
Total number of extra stickers received by the rest of the girls
= 7 x 12
= 84
Total number of stickers given up
= 6 x 7 u
= 42 u
42 u = 84
1 u = 84 ÷ 42 = 2
Total number of stickers for 13 girls
= 13 x 10 u
= 130 u
= 130 x 2
= 260
Answer: 260
