What will be the minimum possible average of Group A if 5 students are transferred from A to B?1). 19.332). 21.53). 22.54). 20.5

Answer»

Present total MARKS of Group A = 20 × 20 = 400

Highest score of Group A = 22

Total marks of 5 students of Group A = 22 × 5 = 110

NEW total marks = 400 - 110 = 290

∴ New AVERAGE = $(\frac{{290}}{{15}} = 19.33)$

HENCE, 19.33 is the new average.
