For any integers a and b, min(a, b) and max(a, b) denote the minimum and maximum of a and b, respectively. For example, min(1, 2) = 1 and max(1, 2) = 2. For the integer x, what is the value of max (x, 8)? (1) max(x^2, x) = 16 (2) min(9, x) = x

Find : Value of max (x, 8)= ?
(1) max(x^2, x) = 16 Always x^2 > x ie here x^2 = 16 x= 4 or 4 For both values of x max (x,8 )= 8 max (4,8) =8 and max (4,8 ) =8 Sufficient
(2) min(9, x) = x Here minimum of x and 9 is x => x<9 As x is an integer so maximum value of x =8 and x =<8 so always max (x,8) =8 as is x=8 => max (8,8) =8 if x <8 => max (x,8) =8
Sufficient
Answer: D

(2) min(9, x) = x Here minimum of x and 9 is x => x<9 As x is an integer so maximum value of x =8 and x =<8 so always max (x,8) =8 as is x=8 => max (8,8) =8 if x <8 => max (x,8) =8
Sufficient
Answer: D I don't agree with part (2) here. Min (9,x) => x<=9 , it may be 9,8,7.. So we cannot be sure of the answer using option B.

Question stem did not say that a and b are "distinct" integers. Its just said they are integers. so a and b can be equal. There is no limitation on a and b as per question stem other than integer part.
