## The Attempt at a Solution

I solved this problem and got the correct answer 108 m . But I had to solve a DE . This question is from a test where we get around 1 minute to solve a problem . I took half an hour to solve it .

It looks like a subjective type problem .

I am just curious as to whether there is a quicker/smarter way to find one of the options .
