In doing a division of a question with zero remainder, a candidate took 12 as divisor instead of 21. The quotient obtained by him was 35. The correct quotient is Choose the correct choice
A) 0  B) 12  C) 13  D) 20  E) None
Sol.   Dividend = (12 x 35) = 420.   Now, dividend = 420 and divisor = 21.   ∴ Correct quotient = 420 / 21=
