Answer 1

Answer:

106

Step-by-step explanation:

Let the total number of correct questions be x and total number of wrong questions y,

Therefore, according to question,

x + y = 180 ____________ eq 1

4x - y = 450_____________eq 2

Therefore,

Adding equation 1 and 2, we get,

              x + y = 180

          + 4x - y = 450

_______________________

             5x       = 530

therefore,

 x = 530/5 = 106

Therefore, he answered 106 questions correctly.
