Select the number-pair in which the two numbers are related in the same way as the two numbers of the pair given below. 20 : 68

The relationship is: first number × second number's digit sum equals a consistent pattern. Specifically: 2+0=2, 6+8=14→1+4=5, ratio of number to digit-based value. More directly: 6+8=14=1+4=5, and 20/5=4; similarly 1+2=3 and 3+0=3, 12/3=4. The pair 12:30 follows the same rule.
