Determine the following number
which is divisible by 3?Solution
ATQ, For a number to be divisible by 3, the sum of its digits should be divisible by 3. For option ‘a’: Sum of digits = 4 + 3 + 1 + 6 = 14 (Not divisible by 3) For option ‘b’: Sum of digits = 7 + 5 + 8 + 9 = 29 (Not divisible by 3) For option ‘c’: Sum of digits = 5 + 2 + 1 + 4 = 12 (Divisible by 3) Thus, 5214 is divisible by 3.
