The 5 digit number 2xy89 is the square of an integer then xy is?

Answer 1

We see the last digit of the number is either 3 or 7 so the square has 9 as unit digit
Also we know the number is 3 digit and greater than 140 and less than 180 (by seeing squares)
Thus by elimination we are left with
143,147,153,157,163,167,173,177

The only number satisfying this is 167
167^2 = 27889

So xy = 78
