Given : 47,815 and 2,37,405
To find : Check the divisibility of the given numbers by 3
Solution :
A given number is divisible by 3 iff sum of its digits is divisible by 3.
47,815
Sum of digit = 4 + 7 + 8 + 1 + 5
= 25
25 is not divisible by 3
Hence 47,815 is not divisible by 3
2,37,405
Sum of digits
= 2 + 3 + 7 + 4 + 0 + 5
= 21
21 is divisible by 3
Hence 2,37,405 is divisible by 3
