Question

If it took him 27 minutes and 25 minutes on two of the days how long did it take him on the third day

Answer 1

It took him 23 minutes on the third day.

Explanation:

It took him 27 minutes on the first day.

It took him 25 minutes on the second day.

The difference between the first two days = 25 - 27 = -2

If he continued like this, on the third day it took 25 + (-2) = 23 minutes.

Hence, it took him 23 minutes on the third day.
