Answer
Mark or point of Alex = 91.5
Total points = 126
Percentage of point of Alex = ( 91.5 / 126 ) × 100 %
= 72.6190 %
Case 1:
If 80 % marks have B great then
80 % of 126 = (126/100)×80 = 100.8
Alex required = 100.8 - 91.5 = 9.3 points
So Alex required 9.3 more points to get great B
Case 2:
If 75 % marks have B great then
75 % of 126 = (129/100)×75 = 96.75 point
So Alex required = 96.75 - 91.5 = 5.25
So Alex required more 5.25 points to get great B
