divisible by 3
(a)2040
(b)6395
(c)9604
(d)3692
Answers
Answer:
2040
Step-by-step explanation:
Divisibility test for 3 - all digits should add up to a factor of 3. In this case, only 2+0+4+0=6=3x2.
Given:
Four numbers -
- a. 2040
- b. 6395
- c. 9604
- d. 3692
What To Find:
We have to find that
- Whether the given four numbers are divisible by 3.
How To Find:
To find it, we have to
- First, find the sum of the digits.
- Next, find out whether the number is multiple of 3.
- If yes, then it is divisible by 3.
- If no, then it is not divisible by 3.
Solution:
- a. 2040
Sum of the given digits,
⇒ 2 + 0 + 4 + 0
Add the digits,
⇒ 6
Check whether it is multiple of 3,
⇒ Yes, it is.
∴ Hence, 2040 is divisible by 3.
- b. 6395
Sum of the given digits,
⇒ 6 + 3 + 9 + 5
Add the digits,
⇒ 23
Check whether it is multiple of 3,
⇒ No, it isn't.
∴ Hence, 6395 is not divisible by 3.
- c. 9604
Sum of the given digits,
⇒ 9 + 6 + 0 + 4
Add the digits,
⇒ 19
Check whether it is multiple of 3,
⇒ No, it isn't.
∴ Hence, 9604 is not divisible by 3.
- d. 3692
Sum of the given digits,
⇒ 3 + 6 + 9 + 2
Add the digits,
⇒ 20
Check whether it is multiple of 3,
⇒ No, it isn't.
∴ Hence, 3692 is not divisible by 3.
Final Answer:
a. 2040 is divisible by 3.
b. 6395 is not divisible by 3.
c. 9604 is not divisible by 3.
d. 3692 is not divisible by 3.
