Last year the price range (per kg) for 100 varieties of apples in wholesale market was $1,00. If the prices of each of the 100 varieties increased by 10 percent this year over what it was last year, what is the range of the wholesale prices of the 1000 varieties of apples this year? Options:  A) $ 50  B) $ 100  C) $ 110  D) $600  E) $300
let the lowest price be x.   Therefore, highest price is x +100.   Now price of each variety is increased by 10%.   Therefore the price will remain arranged in the same order as before.   or Lowest price = 1.1x and Highest = 1.1 * (x+100)   or Range = highest - lowest = 1.1 * (x+100) - 1.1x   = 110, Hence, $ 110
