    Question

    From the numbers 583, 459, 687, 754 and 853, which of the following will be the lowest number, if in each number, all the 8s and 5s are replaced with 2 and 1, respectively?

    A.

    459

    B.

    687

    C.

    583

    D.

    853

    Correct option is C

    Given:
    583, 459, 687, 754 and 853
    Now, in each number, all the 8s and 5s are replaced with 2 and 1, respectively.
    So, we get new numbers-
    123, 419, 627, 714 and 213
    So, here we can see 123 is the lowest number. And its original form is 583
    Thus, correct option is (c).
