a is an integer greater than 49 but less than 61, b is an integer greater than 59 but less than 71, what is the range of a/b?  Options
A) 2 / 7
B) 1 / 2
C) 3 / 4
D) 1
E) 5 / 4

Rationale: "min value of a / b will be when b is highest and a is lowest - - - > a = 50 and b = 70 so , a / b = 5 / 7 max value of a / b will be when b is lowest and a is highest - - - > a = 60 and b = 60 so , a / b = 1 range is 1 - ( 5 / 7 ) = 2 / 7 . answer should be a ."
Answer: A
