Choose the numeral pair which is odd and different from others.

Solution

✅ Correct Option: 3

In three pairs, the first number equals the second number multiplied by two less than itself:

23×21=48323\times21=483

26×24=62426\times24=624

38×36=136838\times36=1368

But 31×29=89931\times29=899, not 1023. In fact, 1023=31×331023=31\times33.

So (1023,31)(1023,31) is the odd pair.
