Question

Choose the odd numeral pair.

• A. $12-42$
• B. $14-82$
• C. $23-64$
• D. $36-72$

Answer 1

The correct option is D $36-72$

For pair $(12-42)$

Sum of digits of one number is double of sum of digits of other number.

As, $1+2=3$ and $4+2=6$ which is double of $3$

Similarly,

$1+4=5$ and $8+2=10$ which is double of $5$

$2+3=5$ and $6+4=10$ which is double of $5$

But,

$3+6=9$ and $7+2=9$ which is same as $9$

Odd numeral pair is $(36-72).$

Hence, D is the correct option.
