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 ?
"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 = 87 oa a is the answer ."
subtract(subtract(100, const_3), 5)
