Hi
Parulmahajan89,
In this question you have to note many words,
1) 15 different integers
2) greatest possible integer
Coming to Answer,
Median is 25 and Range is 25 and there are 15 different integers,
_ _ _ _ _ _ _ 25
_ _ _ _ _ _ _
To the left of 25 there should be 7 and to the right of 25 there should be 7 numbers.
But what question say is greatest possible integer. So we need to minimize to the left so that we can get the max number on the right side,
18,19,20,21,22,23,24,25_ _ _ _ _ _ _
And the range given is 25.
Hence max number should be 18+25 = 43.
Hence Answer is
D
