in a series of even consecutive numbers, 30 is the eleventh smallest number and 28 is the thirteenth largest number. what is the range of the series? a)12 b)22 C)30 d)42 e)54

Lets say the series is a,b,c .... , 28, 30, 32, .... 30 is 11th smallest this implies that 28 is 10th smallest 28 is thirteenth largest -----(9 nos)---- 28 ----(12 nos)-- range = 9 + 1 + 12 = 22 Option B

What's the OA?

Hi, I am getting the answer D- 42 28 is the 13th largest, that makes the last number to be 52 If 30 is the 11th smallest, then 10 is the first number. Range: 52-10 = 42. Answer is D Please give the OA and correct me if I am wrong. Bharath-
