a and b are positive numbers such that [#permalink]
As, √(a+b) = 5, So, a + b = 25.

Now As both a and b are positive number, Think of two extreme cases here,
First, a = 0, b = 25, for these values Qnt A = 0, Qnt B = -25, So Qnt A > Qnt B.
Second, a = 25, b = 0, for these values Qnt A = 25, Qnt B = 23, So Qnt A > Qnt B.

So, for the minimum and maximum values for a we get Qnt A is greater than Qnt B, Hence We can deduct for the whole range here.

The answer will be Qnt A.
