Find all the numbers greater than 10 but smaller than 30 , which are divisible by 9 first.
They are 9,18, 27.
If there is a remainder of 2 after beind divided by 9, then the numbers are
11,19,29
Now, for these 3 numbers, which one leaves a remainder of 1 when divided by 4?
The trick is to subtract 1 from each of them first, such that they become divisible by 4.
We get 10,18,28.
And only 28 is divisible by 4. So the number must be 29 to leave a remainder of 1.
