In doing a question of division with zero remainder. a candidate took 12 divisor instead of 21. The quotient obtained by him was 35. The correct quotient is :

Answer: Option D

Divisor taken = 12
Quotient obtained = 35,
Remainder = 0
∴ Dividend = (12 × 35) = 420
Now, Dividend = 420,
Divisor = 21
Remainder = 0
∴ Quotient = $$\frac{420}{21}$$ = 20
