Correct Answer - Option 1 : 4

Numbers between 20 to 60 which are divisible by 3 are:

21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60.

Numbers whose digit's sum is 9:

27, 36, 45, 54

So, 4 such numbers are there between 20 to 60, the sum of whose digits is 9 and are divisible by 3.

Hence, ‘4’ is the correct answer.
