    We need not multiply the last digits even.there are 5x6 which ends with 0 at the end. Any no. multiplied will give 0 at the end . So even by observing we know last digits shall be zero. Options are not two digit nos. so the answer is the last digits is 0, option (a)

    Yes last two digits are the reminder, but the options have only one digit which means the remainder is a single digit that is the last digit. Since the last digit was found to be 0, we can conclude that the last two digits are 0.

    Why not just divide it until the denominator is 1.
    If that's possible, we have the last digit as zero.

    You said divisibility of 100 is depend on the last two digits(00). But later you find the last digit(0) and said the remainder is zero🤔. Please clarify it?

      It is not about that. Look at the options. Its either 0 or 1 or 2 or 4. They are all single digit numbers which means the last digit only will be the remainder. And since the ending digit is 0, the answer is zero. Had it been any option like 30 or 40 or so on, then different method will be used

    If we proceed to multiply the last digits we get 0, 5x5x5x5 is 625, where did we get 0?

    • @AptitudeDestination
      @AptitudeDestination  Рік тому +1

      Theres is a number ending with 6. So 5*6=30, therefore the last digit is 0
