A number when divided by 342 gives a remainder 47. When the same number divided by 19, what would be the remainder ?
There are generally one common thing among almost all such questions i.e. First Divisor (342 in this case) will be a Multiple of Second Divisor (19 in this case). i.e. Remainder with first divisor will always be the remainder with second divisor
Since 342 is a multiple of 19 therefore
If Remainder when Number divided by 343 is 47
then, Remainder when Number divided by 19 will be 47 (which can further be divided to finally calculation the final remainder) = Remainder (47/19)=9
Another method is to find a number that satisfies the first condition and calculate the remiainder with second divisor
i.e. Number when divided by 342 gives remainder 47
i.e. one of the numbers of such tyoe can be 342+47 = 389
now divide 389 by 19 and see the remainder Remainder (47/19)=9
