25 of their share, the rest of the pupils received 7 more stickers each. How many stickers were there in the bag?

| Value |
2 u |
7 |
5 u |
| Total value |
14 u |
42 |
65 u |
Number of pupils who received the extra stickers
= 13 - 7
= 6
Total number of extra stickers received by the rest of the pupils
= 6 x 7
= 42
Total number of stickers given up
= 7 x 2 u
= 14 u
14 u = 42
1 u = 42 ÷ 14 = 3
Total number of stickers for 13 pupils
= 13 x 5 u
= 65 u
= 65 x 3
= 195
Answer: 195
