intial or final selling price not mentioned in question

Question:
With a 5% discount on the cost of sugar, a buyer could purchase 2 kg more sugar for Rs.608. New selling price of sugar is: 
Options:
A) Rs.15.50
B) Rs.15.20
C) Rs.16.50
D) Rs.16
Solution:

Let Initial Price of sugar was X.
After Discount of 5%, the price of the sugar become,
= X - 5% of X .
= X - (5X/100).
= (100X - 5X)/100.
= 95X/100. 
Amount of sugar now, buyer gets in Rs.608,
= 608/(95X/100).
= (608 *100)/95. 
Amount of sugar he gets before the discount,
= 608/X.
Now, According to question,
608/(95X/100) - 608/X = 2.
On Solving,
X = Rs. 16.

New selling price=16-16*5/100=15.20
