On dividing a number by 5, we get 3 as remainder. What will the remainder when the square of the this number is divided by 5 ?  Choose the correct choice from the following answers:
A) 0	B) 5	C) 8	D) 9	E) 4
Explanation:   Let the number be x and on dividing x by 5, we get k as quotient and 3 as remainder.   x = 5k + 3   x^2 = (5k + 3)^2   = (25k^2 + 30k + 9)   = 5(5k^2 + 6k + 1) + 4   On dividing x2 by 5, we get 4 as remainder.   4)
