Dear Sunindra,

The data given is insufficent,

Concentration of a solution can be expressed in terms of percentage composition. It is based on the             weight or volume of the components of solution.
Weight / Weight %
 
   2% w / w solution means grams of solute is dissolved in 100 grams of solution.
Weight / volume %
 
   4% w / v solution means 4 grams of solute is dissolved in 100 ml of solution.
Volume / weight %
 
   3% v/ w solution means 3 ml of solute is dissolved in 100 grams of solution.
Volume / volume %
