Answer:
84 answers correct
Step-by-step explanation:
Let us suppose the no. of correct answers is x and wrong answers be y
Then -
x + y = 120
and
5x - 2y = 348 according to the given two conditions
solving eq. 1
x = 120 - y
putting this value in eq. 2
5 (120-y) - 2y = 348
600 - 5y -2y = 348
-7y = 348 -600 = -252
y = -252 / -7 = 36
so, x = 120 - 36 = 84
so, he answered 84 correct and 36 wrong answers.
