Answer:
let marks for correct answer that is 5 be = x
and let the number given for wrong answer that is -2 be = y
then Ram's score = 3x + 4y
= 3(5) + 4(-2)
= 15 - 8
= 7
therefore ram scored 7 marks.
hope it helps
have a great day ahead <3

Answer:
7 marks
Step-by-step explanation:

(-2) marks are given for every incorrect answer
Right answers by Ram=3 which= 3*(+5)=15 marks
Wrong answers by Ram=4 which=4*(-2)=(-8)marks
Total marks = Sum of all marks
(+15)+(-8)
