Mila is playing with some digit cards that are numbered from 1 to 10 and some digit cards have vowels written on them. She wants to make a 3 digit code in which tens place is occupied with a vowel that lies from A to P, ones place is occupied by either 2 or 4 and hundreds place is occupied by any of the odd number digits. What are the possible ways in which such a code can be formed?

There are 5 odd digits (1, 3, 5, 7, 9) for the hundreds place, giving 5 options. The vowels from A to P are A, E, I and O, giving 4 options for the tens place. The ones place must be 2 or 4, giving 2 options. The total number of possible codes is 5 times 4 times 2, which equals 40.
