Answer:

900

dekh bhai

square ke last me 20,40,60,80,00

hona chahiye(so that it is divisible by 20)

or 9 se bhi divisible hona chahiye toh simply ye 180 ki table se HOGA(i.e.180,360,540,720,900)

ye saare 15 se toh divisible honge hi kyunki 15 ka 3 toh 9 mai aa gya or 5 bhi 20 main aa gya.

So is table mein smallest square 900 hi H
