Which of the following numbers are divisible by 3? Options: a) 254 b) 387 c) 1395

Answer 1

b . 387 is the answer.

Answer 2

If you want to find the number divisible by 3, then add the digits of a given number and then check whether it is a factor of 3 or not. If the addition is factor of 3 then the number is divisible by 3.

In this case

254 = 2 + 5 + 4 = 11 Not a factor of 3, so it is not divisible by 3
387 = 3 + 8 + 7 = 18 Divisible by 3, so the number is also divisible by 3 and reminder is 129
1395 = 1 + 3 + 9 + 5 = 18 Divisible by 3, so Number is also divisible by 3 and the reminder is 465

therefore, 387 and 1395 are the numbers divisible by 3.
