A bag of stickers was distributed equally among 18 students. When 10 of these students gave up
23 of their share, the rest of the students received 10 more stickers each. How many stickers were there in the bag?

| Value |
2 u |
10 |
3 u |
| Total value |
20 u |
80 |
54 u |
Number of students who received the extra stickers
= 18 - 10
= 8
Total number of extra stickers received by the rest of the students
= 8 x 10
= 80
Total number of stickers given up
= 10 x 2 u
= 20 u
20 u = 80
1 u = 80 ÷ 20 = 4
Total number of stickers for 18 students
= 18 x 3 u
= 54 u
= 54 x 4
= 216
Answer: 216
