Question
If r and s are two digits of the number 65723rs such that this number is divisible by 40, then r + s = ?
(A) 6
(B) 3
(C) 2
(D) 4
Solution
For a number to be divisible by 40, it must end in 00. This is because 40 is a multiple of 10, and any number that is a multiple of 10 ends in 0. Therefore, in the number 65723rs, r must be 0 and s must also be 0 for the number to be divisible by 40.
So, r + s = 0 + 0 = 0.
However, 0 is not an option in the multiple choices provided. There seems to be a mistake in the question or the options provided.
