JEE 2023 — Mathematics PYQ

JEE | Mathematics | 2023

Total numbers of 3-digit numbers that are divisible by 6 and can be formed by using the
digits 1, 2, 3, 4, 5 with repetition, is _____.

Choose the correct answer:

Explanation

Given numbers are 1, 2, 3, 4, 5
Now, a number is divisible by 6, if it is divisible by both 3 and 2.
Case I: If 2 is at unit place, then possible pairs of first two places are (1, 3), (3, 1), (2, 2), (2, 5), (5, 2), (3, 4), (4,
3), (5, 5)
Case II: If 4 is at unit place, then possible pairs of first two places are (1, 1), (1, 4), (4, 1), (2, 3), (3, 2), (4, 4), (3,
5), (5, 8)
Hence, total numbers are 8 + 8 = 16
