It will also be a multiple of 21 .
As it is divisible by 3 the first possibility is 366 so:-
364 + n = 21m
where n = 2,5,8,11,14...
Trying each number in turn we get:-
364 + 14 = 21m
21m = 378
m = 18
so the answer is 378

Step-by-step explanation:
3c + 1a = 65
3c + 3a = 111
a = 65-3c
3c + 3(65-3c) = 111
3c + 195 -9c = 111
-6c = -84
c = 14
3(14) + a = 65
42 + a = 65
a = 23
