Answer 2

There are 30 two digits divisible by 3.

Explanation:

The multiples of 3 is 3, 6, 9, 12, 15, 18, 21, 24, 27, 30.....99.

The lowest 2 - digit number is 12.

The highest 2 - digit number is 99.

We know that arithmetic progression(A.P) formula for finding the nth term as aₙ = a + (n - 1)d

where aₙ = highest number, a = lowest number, d = difference (3)

99 = 12 + (n - 1) x 3

99 - 12 = 3n - 3

87 + 3 = 3n

90 = 3n

n = 30.

Therefore, there are 30 two digits divisible by 3.
