⅓ = 5/15
Total = 15u
Answered = 5u
Remaining = 10u
Answered = 14 questions
Left = 10u-14
Answered : left = 4:1= 12:3 (note: make total =15u)
Therefore ,left
10u-14=3u
7u =14
1u = 2
At 1st = 15u =15×2= 30 questions.

Sorry but how did you know total is 15u? How to get 15u?
1/3
If you draw model, you will draw 3u.,meaning total (all) =3u.
1/3 multiple 5/5 (x5 on numerator and denominator) = 5/15
Meaning total 15u.
To can draw model for his question. Let me know if you need model method.
