Let price be x
The store owner decided to raise the price of a particular item by exactly 10%,
so the new price must be = x *110 /100
= 1.1x
So, The new number must be 1.1 times the original price.
here,
option A 10* 1.1 = 11 $
option B 8 * 1.1 = 8.80 $
option D 71 * 1.1 = 78.1 $ can be new prices
Now, check option (c)
1.1x = 57.30
So, x = 57.30/1.1 ~ 52.09 (Approximately)
So (C) cannot be new price
