Question
For which of the following students, is it not possible to determine the exact number of subjects in which they obtained a grade point of 2?
Answer: Option D
:
D
Student A:
Total grade points (in remaining two subjects) = 10 - 4 = 6. Three possibilities exist.
(1)6 = 3 + 3
(2)6 = 4 + 2
(3) 6 = 5 + 1
Student A satisfies the given condition.
Student B:
Total grade points (in remaining three subjects) = 15 - 6 = 9. Possibilities .
(1) 9 = 3 + 3 + 3
(2) 9 = 4 + 3 + 2
(3) 9 = 5 + 3 + 1
(4) 9 = 4 + 4 + 1
Student B satisfies the condition. Hence option (d)
