The concentration of spirit in three different vessels A, B and C are 30%, 30% and 25% respectively. If 4 litres from vessel A, 5 litres from vessel B and 6 litres from vessel C are mixed, find the concentration of spirit in the resultant solution. Choose the correct choice from the following answers.
A) 32%
B) 33%
C) 34%
D) 35%
E) 28%
Quantity of spirit in new solution=(4*30/100)+(5*30/100)+(6*25/100)=1.2+1.5+1.5=
