Problem 1:

Peter had 41 marbles. Mike gave Peter some more marbles and then he had 65 in all. How many marbles did Mike give Peter?

#### Solution:
1. Peter initially had 41 marbles.
2. After receiving marbles from Mike, Peter had a total of 65 marbles.
3. To find out how many marbles Mike gave Peter, we need to subtract the initial number of marbles Peter had from the total number of marbles he ended up with:
\[
\text{Marbles given by Mike} = \text{Total marbles after} - \text{Initial marbles}
\]
\[
\text{Marbles given by Mike} = 65 - 41 = 24
\]

#### Answer:
\[
\boxed{24}

Problem 2:

Tess picked 12 flowers on Monday morning. In the afternoon she picked some more flowers. If Tess picked 27 flowers in all, how many did she pick in the afternoon?

#### Solution:
1. Tess picked 12 flowers in the morning.
2. She picked a total of 27 flowers throughout the day.
3. To find out how many flowers she picked in the afternoon, we subtract the number of flowers she picked in the morning from the total number of flowers:
\[
\text{Flowers picked in the afternoon} = \text{Total flowers} - \text{Flowers picked in the morning}
\]
\[
\text{Flowers picked in the afternoon} = 27 - 12 = 15
\]

#### Answer:
\[
\boxed{15}

Problem 3:

Peter read 34 pages of his book before lunch. After lunch he read some more. If Peter read 56 pages in all, how many pages did he read after lunch?

#### Solution:
1. Peter read 34 pages before lunch.
2. He read a total of 56 pages throughout the day.
3. To find out how many pages he read after lunch, we subtract the number of pages he read before lunch from the total number of pages:
\[
\text{Pages read after lunch} = \text{Total pages} - \text{Pages read before lunch}
\]
\[
\text{Pages read after lunch} = 56 - 34 = 22
\]

#### Answer:
\[
\boxed{22}
\]

Jess gave out 21 cookies to the girls in her class. She then gave out cookies to the boys in her class. If Jess gave out 45 cookies in all, how many cookies did she give out to the boys?

#### Solution:
1. Jess gave out 21 cookies to the girls.
2. She gave out a total of 45 cookies.
3. To find out how many cookies she gave out to the boys, we subtract the number of cookies given to the girls from the total number of cookies:
\[
\text{Cookies given to boys} = \text{Total cookies} - \text{Cookies given to girls}
\]
\[
\text{Cookies given to boys} = 45 - 21 = 24
\]

#### Answer:
\[
\boxed{24}
\]
