Question

Sally likes 225 but not 224; she likes 900 but not 800; she likes 144 but not 145. Which does she like

Answer 1

Ans.

It's a simple question though. Okay. I am giving the simple answer atfirst. Sally likes 225 (square of 15), 900 (square of 30) and 144 (square of 12). She loves perfect square terms indeed.

Now, I want to think out of the box.
225 = 15 × 15
900 = 30 × 30
144 = 12 × 12
Every term has a common multiple 3 (you can also take 9, as 9 is also a common multiple). Therefore, Sally likes 3.

Math is really a fun when we imagine out of the box.
