Question 21201
to be divisible by 3, the digits must add up to a number that is itself divisible by 3.


So 271 --> 2+7+1 = 10, which is not disible by 3, so neither is 271.


note the 2+7 add up to 9, so the value of d must be a 3, 6 or 9 to keep this rule.


Any number divisible by 4 has to be even, so this means of the 3 options, 273, 276 or 279, we are left with just 276.
