If the value of x is less than 5, then after rounding the value will be 47,
but if the value if x is more than 4 then after rounding the value will be 48.

As per the given condition x > y. Hence x cannot take the value of 0.

Statement 1: The sum of x and y is 6

Three cases are possible

(i) x,y = 6,0 --> Value after rounding is 48
(ii) x,y = 5,1 --> Value after rounding is 48
(iii) x,y = 4,2 --> Value after rounding is 47

As we see multiple cases, this statement is not sufficient.

Statement 2: The product of x and y is 5.

As we know x>y, the only possible case is x,y = 5,1. So after rounding the value is 48.

Statement 2 is sufficient.
