Question

Find the odd pair out of the given alternatives.

• A. $22:0$
• B. $24:12$
• C. $23:5$
• D. $24:18$

Answer 1

The correct option is D $24:18$

In all other groups except $24:18$,

second number is the difference of the square of the digits of the first number.
(A) $2^2-2^2=4-4=0$
(B) $4^2-2^2=16-4=12$
(C) $3^2-2^2=5$

But option D doesn't follow this pattern.

(D) $4^2-2^2=12$.

So, option D.
