What is the solution to these two tasks?

1. Poor Easter bunny

The cunning fox will only let the hard-working Easter Bunny into the village if he gives him 8 Easter eggs as well every time he leaves the forest for the village. When the Easter Bunny arrives back at his hiding place in the forest, the remaining eggs in his basket are automatically doubled. When he passes the fox for the third time, he gives him his last 8 eggs and continues on his way to the village with an empty basket.

how many Easter eggs did the rabbit have in his basket when he came to the fox for the first time?

2.Sibling love

Sven Müller has just as many brothers as sisters. His sisters have half as many sisters as brothers?
