Aptitude | Arithmetic Aptitude 5 | Question 5 - GeeksforGeeks | 28 Jun, 2021
The product of two numbers is 108 and the sum of their squares is 225. The difference of the number is:
(A) 5(B) 4(C) 3(D) None of theseAnswer: (C)Explanation:
Let the numbers be x and y.
Then xy = 108 and x2 + y2 = 225
(x –y)2 = x2 + y2 – 2xy
(x –y)2 = 225 – 216
(x –y)2 = 9
Therefore (x –y) = 3
