she do 14 quest. incorrect
14*2=28
total marks of Jaya = 64- 28=36
Answer:
36
Step-by-step explanation:
Given that,
Total questions= 30
Mark for a correct answer = 4
Mark for a incorrect answer = (-2)
Number of questions attempted by Jaya = 30
No. of correct answers given = 16
No. of incorrect answers given = 30 - 16
= 14
Mark scored for 16 correct answers = 16×4
= 64
Mark scored for 14 incorrect answers = 14×(-2)
= (-28)
Total mark scored by Jaya = 64+(-28)
= 64-28
= 36
