Total number of stickers bought -> 60u (LCM of 3, 4, 5)
| Star-shaped stickers | Heart-shaped stickers | |
| At first | ¾ × 60u = 45u | ¼ × 60u = 15u |
| Used | 2/5 × 45u = 18u | 1/3 × 15u = 5u |
| Remaining | 45u – 18u = 27u | 15u – 5u = 10u |
27u + 10u = 111
37u = 111
u = 3
Total number of stickers bought -> 60u = 180
