B. 70%

C. 75%

D. 80%

E. 90%

1st section: 40 questions
2nd section: 80 questions
TOTAL number of questions = 120

The student correctly answered 70 percent of all the questions in the test
70% of 120 = 84
So, the student correctly answered 84 questions

The student correctly answered 60 percent of the questions in the second section
The 2nd section has 80 questions
60% of 80 = 48
So, the student correctly answered 48 questions in the second section

What percent of the questions did the student correctly answer in the first section?
84 - 48 = 36
So, the remaining 36 questions the student answered correctly much have been in the first section.
There are 40 questions in the first section.
36/40 = 9/10 = 90%

Cheers,
Brent
