There are $3$ classes having $20, 25$ and $30$ students respectively having average marks in an examination as $20, 25$ and $30$, respectively. If the three classes are represented by A, B and C and you have the following information about the three classes.

A $\to$Highest score $22$, Lowest score $18$
B $\to$Highest score $31$, Lowest score $23$
C $\to$ Highest score $33$, Lowest score $26$

What will be the minimum possible average of group A if $5$ students are transferred from A to B?
