Which of the following numbers is divisible by 7?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 3661.
The divisibility rule of 7 states that, if a number is divisible by 7, then “the difference between twice the unit digit of the given number and the remaining part of the given number should be a multiple of 7 or it should be equal to 0.
Using the concept:
⇒ 3661 = 366 - 2
⇒ 364 = 36 - 8 = 28
We know that 28 is a multiple of 7.
Hence, the required number is 3661.
