Should be 'A'.
Thanks very good, fast and logical explanation.
Average is 150k. Total value = 15*150k = 2250k
The median is 130k.
To evaluate the stmt I:
Eight homes are with values 130k each. The remaining 7 will be of total value 1210k. This means the costliest home will have the value at least of 1210/7 = 170k (approx).
Hence the statement I is true.
II and III are not necessarily true.[/b]
