How many eggs?

Picture down below

:D

27

Step-by-step explanation:

27 is less than 40 and 2+7 = 9. It's also and odd number. 18 isn't it, even though the digits in the number add up to 9, because it's even.

All multiples of 9 have digits that add up to 9. All the rest are above 40 or even so you can eliminate them all right away.

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !
