If you have two straight sticks of length 7.5 feet and 3.25 feet

If you have two straight sticks of length 7.5 feet and 3.25 feet, what is the minimum length can your measure?

Answer: C

It is given that:

Length of stick S1 = 7.5 feet and Length of stick S2 = 3.25 feet

To get the minimum length which you can measure, use stick S2 and measure the length of stick S1.

Total length of S1 = 3.25 + 3.25 + remaining length of S1

6.5 + remaining length of S1 = 7.5

Remaining length of S1 = 7.5 - 6.5 = 1 foot

Hence, the minimum length which we can measure is 1 foot.
