Answer

Answer:

14

Explanation:

Step1: Check each digit

Check each digit in the 20 - group of 4 - digit numbers for 2, 4, 8.

Step2: Count occurrences

Count the number of times 2, 4, 8 appear. In 7918: 1 (digit 8) In 7910: 0 In 2546: 2 (digit 2 and 4) In 1390: 0 In 6075: 0 In 1230: 1 (digit 2) In 2386: 2 (digit 2 and 8) In 0793: 0 In 7359: 0 In 3048: 2 (digit 4 and 8) In 2816: 2 (digit 2 and 8) In 6147: 1 (digit 4) In 5978: 1 (digit 8) In 5621: 1 (digit 2) In 9732: 1 (digit 2) In 9436: 1 (digit 4) In 3806: 1 (digit 8) In 5971: 0 In 6173: 0 In 1430: 1 (digit 4) Total = 14.
