A boy standing on the third stair on a staircase goes up by five more stairs. Which stair is he standing at now? At which step will he be after he comes down by 2 stairs
Solution:
To solve the given word problem firstly we have to understand and explore it. We will first focus on the given parameters and then frame a strategy around it to solve the question.
It is given that,
Boy is currently at the third stair = +3
Same boy goes up 5 stairs in the same direction = +5
Therefore, 3 + 5 = 8. This gives his current position that he is at 8th stair.
Further the problem says the boy comes down by 2 stairs.
This means if he is at 8th stair then he comes down in the opposite direction i.e. down by 2 stairs (i.e. -2).
This gives, 8 + (-2) = 8 - 2 = 6.
The boy is at 6th step now.
✦ Try This: Can you find the position of the boy if he comes down further by 3 more stairs
Using the same logic as above and analysing the problem using integer rules we can determine the position of the boy if he comes down further by 3 more stairs.
