Average = total score / number of tests

total score = 180 + 150 = 330
50% average = 330 * 0.5 = 165 ( he needs to score this )
He has scored 30% in the first test with 180 marks
so he has already scored 0.3 * 180 = 54
Now He needs to score 165-54 = 111 in the second test.
So the precentage = 111/150 = 74
( 0.74 * 150 = 74 * 1.5 = 74 + 74/2 = 74 + 37 = 111 )
