Solution
The correct option is A 6, 5, 3 Given,
To find the missing numbers, let's start from the ones places.
The floor reached after the 1st jump is subtracted from 6 to get 0. We can represent this as:
6 - 1st jump = 0
1st jump = 6 - 0
1st jump = 6
Moving to the tens places, we can see that they are already filled. So, we move to the hundreds places.
3 is subtracted from the 2nd jump floor number to get 1. However, one is borrowed by the tens place. We can represent this as:
(2nd jump - 1) - 3 = 1
2nd jump - 4 = 1
2nd jump = 1 + 4
2nd jump = 5
Moving to the thousands places,
4 is subtracted from 7 to get the 3rd jump floor number. We can represent this as:
