Dividend =( divisor) X q + remainder.

Given:
Divisor = 12 , Quotient = 35, Remainder = 0 (Wrong data)
Divisor = 21 (Truedata)
Putting Wrong information in Formula We will get Dividend,
dividend = 12 x 35 = 420.
we know true Divisor.
Again By formula,
420/21 = 20 <==ANS.

35*12 = 420,
Quotient = 420/21 = 20.
