A store owner decided to raise the price of a particular item by exactly 10%. Of the following which is NOT the new price?

a) $1.10
b) $8.80
c) $11.00
d) $57.30
e) $78.10

• d) $ 57.30
  
  If price of an item=x, then with 10% increase new price=(110/100)*x=1.1x
  So among the given option all the values multiple of 1.1 can be the new price except 57.30

• Previous Price % New Price(previous price+percentage value)
  ----------------- -------------- -------------
  a --> $1 10% ($ 0.1) $ 1.10
  b --> $8 10% ($ 0.8) $ 8.80
  c --> $10 10% ($ 1.0) $11.00
  e --> $71 10% ($ 7.1) $78.10
  
  So, all the above options fit into 10%.
  
  But for option d --> $52 10% ($5.20) %57.20
  
  So, 57.30 is not exact 10%.
