Rozer a great tennis player has $10$ boxes with him, which have an average of $25$tennis balls per box. If each box has at least $8$ balls and no two boxes have an equal numbers of balls, then what is the maximum possible numbers of balls in any box ?

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?

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, answer the question that follows:

A $\to$highest score $22$, lowest score $18$
B $\to$highest score $31$, lowest score $23$
C $\to$highest score $33$, lowest score $26$

Which of these will definitely not constitute an operation for getting the minimum possible average value for group A?

B $\to$highest score $31$, Lowest score $23$
C $\to$highest score $33$, Lowest score $26$

If we set the highest possible average of class C as the primary objective and want to achieve the highest possible value of class B as the secondary objective, what is the maximum value of class B's average that is attainable ? (Assume there are only 5 students who scored highest score & 5 students who scored lowest scores).
