1 u + 10 |
1 u |
Total number of stickers
= 95 + 75
= 170
Total number of stickers in the end = 1 u + 10 + 1 u = 2 u + 10
The total number of stickers at first and in the end remains unchanged.
2 u + 10 = 170
2 u = 170 - 10 = 160
1 u = 160 ÷ 2 = 80
Number of stickers that are transferred from Box J to Box K
= Number of stickers in Box K in the end - Number of stickers in Box K at first
= 80 - 75
= 5
Answer(s): 5
