A computer routine was developed to generate two numbers, ( x,y), the first being a random number between 0 and 100 inclusive, and the second being less than or equal to the square root of the first. Each of the following pairs satisfies this routine EXCEPT:

(A) (99, 10)
(B) (85, 9)
(C) (50, 7)
(D) (1 , 1)
(E) (1, 0)

10^2 = 100 which is more than 99, hence the pair (99,10) does not satisfy the given condition.

Option A

99 is slightly less than 100, which has a square root of 10. Square root of 99 is therefore less than 10, so answer is B

Hey amhill4, did you mean to write A instead of B?

I need help as when i read the question , the second should be less than or equal to square of first.

so if its (X,Y) then y<=X2???

Hi Ana4001

It is "second being less than or equal to the square root of the first", i suppose you missed out on the bold part

it means y <= $$\sqrt{x}$$

Looking at the answer choices, we see that since √100 = 10, square root of 99 is less than 10, so (99,10) cannot be the pair of numbers chosen.
