After |
1 u + 15 |
1 u |
Total number of stickers
= 100 + 75
= 175
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 = 175
2 u = 175 - 15 = 160
1 u = 160 ÷ 2 = 80
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
= 80 - 75
= 5
Answer(s): 5
