Explanation:

Let the number be N.

∴ N = 4a + 2 i.e., N can be 2, 6, 10, 14, 18, ….

Also, N = 5b + 4 i.e., N can be 4, 9, 14, 19, …

The least possible value of N = 14.

∴ N = k × LCM(4, 5) + 14 = 20k + 14.

Now we have to find the least three-digit such number.

For k = 5, N = 114 (least three-digit such number).

Hence, 114.
