After |
1 u + 35 |
1 u |
Total number of stickers
= 85 + 40
= 125
Total number of stickers in the end = 1 u + 35 + 1 u = 2 u + 35
The total number of stickers at first and in the end remains unchanged.
2 u + 35 = 125
2 u = 125 - 35 = 90
1 u = 90 ÷ 2 = 45
Number of stickers that are transferred from Box W to Box X
= Number of stickers in Box X in the end - Number of stickers in Box X at first
= 45 - 40
= 5
Answer(s): 5
