Radio= the 15th highest price and the 20th lowest price

means 14 items priced higher than radio and 19 lower that its price


so items=14+19+1 (radio )=34

Assume items arranged in increasing price order

1-19----20itemradio-------highestpricelast item

If the 20th item is also the 15th item from right then there must be 14 items after the 20th one.

19+1+14 = 34

Friendly tip: Always transfer details (given data or whatever) on to the scratch paper as sometimes a simple diagram as this can make things clearer or worse :-) Jus kidding....

Good luck.
