Answer:

The test has 140 questions. This can be split into two sections of 80 and 60 questions.

To score 60% in the test he should get 60*140/100 = 84 questions correct.

In the first 80 questions he got 70% correct or 56 of them were correct.

In the remaining 60 questions he should get 28*100/60 = 47 questions right, percentage-wise it is 47*100/60 or 78%.
