After |
1 u + 20 |
1 u |
Total number of stickers
= 85 + 45
= 130
Total number of stickers in the end = 1 u + 20 + 1 u = 2 u + 20
The total number of stickers at first and in the end remains unchanged.
2 u + 20 = 130
2 u = 130 - 20 = 110
1 u = 110 ÷ 2 = 55
Number of stickers that are transferred from Box V to Box W
= Number of stickers in Box W in the end - Number of stickers in Box W at first
= 55 - 45
= 10
Answer(s): 10
