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).
