Given :-
5 marks are awarded for every correct answer
(-2) marks are awarded for every incorrect answer
0 for questions not attempted

Now

Mohan gets 4 correct and 6 incorrect answers.

(4×5) + [6×(-2)]
20 -12
=8

So he score 8 marks in the class test.

so = According to question

(5×5) + (5×-2)
25 - 10
= 15

Hence she score 15 marks in the class test.

3)Heena gets two correct and five incorrect answer out of seven questions she attempts.

(2
×5) + (5×-2) + (3×0)
10 - 10
=0
