If 5 students are transferred from A to B, the maximum possible average achieved for group A will be1). 20.662). 21.53). 20.754). 20.5

Answer»

For maximum achievable average of Group A STUDENTS with lowest MARKS should be transferred.

Lowest marks of Students in Group A = 18

Present total marks = 20 × 20 = 400

Average of 5 students transferred = 18 × 5 = 90

New total marks = 400 - 90 = 310

∴ Average maximum marks of Group A = $(\frac{{310}}{{15}} = 20.66)$

∴ 20.66 is the new maximum average of Class A.
