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 above the three cases, answer the questions that follow:
A’s highest score 22, Lowest score 18
B’s highest score 31, Lowest score 23
C’s highest score 33, Lowest score 26
If five students are transferred from A to B.
If 5 students are transferred from B to A, what will be the minimum possible average of A?
1). 20.69
2). 21
3). 20.75
4). 20.6
This Question has 1 answers.
Lowest score of B $= 23$
Present total marks of $A = 20 × 20 = 400$
Marks of $5$ students of $B = 23 × 5 = 115$
New total marks of $B = 400 + 115 = 515$
New average of B = $(\frac{{515}}{{25}} = 20.6)$
Hence, $20.6$ is the new minimum average of $A$.
