After |
1 u + 15 |
1 u |
Total number of stickers
= 85 + 50
= 135
Total number of stickers in the end = 1 u + 15 + 1 u = 2 u + 15
The total number of stickers at first and in the end remains unchanged.
2 u + 15 = 135
2 u = 135 - 15 = 120
1 u = 120 ÷ 2 = 60
Number of stickers that are transferred from Box G to Box H
= Number of stickers in Box H in the end - Number of stickers in Box H at first
= 60 - 50
= 10
Answer(s): 10
