N is 1/2
L is 1/4 of the remaining 1/2
F is 3/5 of the remaining 3/4
SO we have to work backwards.
For F:
2 units is 6 questions, so 1 unit is 3,
5 units is 15 questions
For L
3 units is 15 questions, so 1 unit is 5,
4 units is 20 questions
For N
1 is 20, so 2 units is 40 questions.
The answer is 40 question.
