Set X consists of all two-digit primes and set Y consists of all positive even multiples of 5 less than 100. If the two sets are combined into one, what will be the range of the new set?
Choose the correct choice
A) 87  B) 89  C) 90  D) 92  E) 95
Set X = {11, 13, 17,............., 83, 89, 97}   Set Y = {10, 20, 30,..............., 70, 80, 90}   Combining two sets, say Set Z   Set Z = { 10,11, 13, 17, 20,30,..................., 70, 80, 83, 89, 90, 97}   Range = Max Value - Min Value   Range (Z) = 97 - 10=
