Question

which of the following is divisible by 7 ? a 4277 b) 3513 c) 862 d) 4675​

Answer 1

Answer:

option a is answer.

4277/7=611

Answer 2

Answer:

4277

Step-by-step explanation:

Divisibility rule of 7 ---> Take the last digit of the number and double it. Then subtract the result from the rest of the number. If the resulting number is evenly divisible by 7, the original number is also divisible by 7 (if the last 2 digits are 00, remove all zeros and then take the last 2 digits).

a.) 4277

=> Last 2 digits = 77

Doubling it, 77*2 => 154.

As 154 is divisible by 7, 4277 is divisible by 7.

b.) 3513

=> Last 2 digits = 13

Doubling it, 13*2 => 26

As 26 is not divisble by 7, 3513 is not divisible by 7.

c.) 862

=> Last 2 digits = 62

Doubling it, 62*2 => 124

As 124 is not divisible by 7, 862 is not divisible by 7.

d.) 4675

=> Last 2 digits = 75

Doubling it, 75*2 => 150

As 150 is not divisible by 7, 4675 is not divisible by 7.

Thus, a.) 4277 is divisible by 7.
