Which of the following are divisible by both 2 and 3?

III. 5,555,554,673

A. I only

B. I and II

C. II and III

D. II Only

E. I and III

Divisibility rule of 2: The number should be even or the last digit should be divisible by 2

Divisibility rule of 3: The sum of all the digits of the number should be divisible by 3

I. 234,124,422

Last digit -2. This is divisible by 2

Sum of digits = 24. This is divisible by 3

Hence the number is divisible by both 2 and 3

II. 88,865,544,264

Last digit -2. This is divisible by 2

Sum of digits = 60. This is divisible by 3

Hence the number is divisible by both 2 and 3

III. 5,555,554,673

Last digit - 3. This is not divisible by 2.

Hence only I and II are divisible by both 2 and 3

Correct Option: B
