Q12. If x is greater than or equal to 15 and y is less than or equal to 20, then which one of the following is always correct?
(a) x is greater than y
(b) (y – x) is greater than 5
(c) (y – x) is less than or equal to 5
(d) (x + y) is greater than or equal to 35
Correct answer: (c)
Explanation:
Max value of (y-x) is when y is max and x is min
Max value of y = 20
Min value of x = 15
So, max value of (y-x) = 20 - 15 = 5
Thus, (y – x) is less than or equal to 5
