1 u + 25 |
1 u |
Total number of stickers
= 95 + 30
= 125
Total number of stickers in the end = 1 u + 25 + 1 u = 2 u + 25
The total number of stickers at first and in the end remains unchanged.
2 u + 25 = 125
2 u = 125 - 25 = 100
1 u = 100 ÷ 2 = 50
Number of stickers that are transferred from Box C to Box D
= Number of stickers in Box D in the end - Number of stickers in Box D at first
= 50 - 30
= 20
Answer(s): 20
