After |
1 u + 30 |
1 u |
Total number of stickers
= 95 + 45
= 140
Total number of stickers in the end = 1 u + 30 + 1 u = 2 u + 30
The total number of stickers at first and in the end remains unchanged.
2 u + 30 = 140
2 u = 140 - 30 = 110
1 u = 110 ÷ 2 = 55
Number of stickers that are transferred from Box Q to Box R
= Number of stickers in Box R in the end - Number of stickers in Box R at first
= 55 - 45
= 10
Answer(s): 10
