1 has to be true
median is 130000-> so, max we have 8 houses at 130000 and 7 houses at 225000-(8*130000)
so 7 houses are to be sold at 121000 or avg price of 121000/7=173000.
even if we were to decrease, atleast one house will be sold at 165000.

2 need not be true, as from the above example
we have 8 houses at 130000 and 7 houses at 173000 total of 2250000

3 also need not be true
bcos of the example above.

so ans is A

The median is 13,000 so III must be true

Because III is true, and the average is 15,000 so with any house is less than 13,000, (less 2000 below 15,000), there is a house cost more than 17,000 ( more 2000 above 15,000) => I must be true
