Given that K = {8, x, y, 10} and mean of set K is 12, there is no mode, and x > y
Quantity A: x + y
Theory: Mean of a set = (Sum of All the Values) / (Total Number of Values)
=> Mean of Set K = \(\frac{8 + x + y + 10 }{4}\) = 12 (given)
=> 18 + x + y = 4*12 = 48
=> x + y = 48 - 18 = 30
Clearly, Quantity A(30) > Quantity B(24)
So, Answer will be A
Hope it helps!
