Hi there !!
The square of the number whether odd or even will be decided from the digits present in the units place,
So,
a) 209
Number in the units digit= 9
Square of 9 = 9² = 81
so,
the square of 209 will have 1 in units place.
b) 2365
Number in units digit = 5
Square of that number = 5² = 25
Thus ,square of 2365 will have 5 in units digit.
c) 774
Number in units digit = 4
Square of the number = 4² = 16
Thus, square of 774 will have 6 in units place
