Now, Esthie is three times as old as her daughter Zissy.

10 year ago, Esthie was 7 times as old as Zissy.

How old was Esthie when she had Zissy?

How old is Esthie now? How old is Zissy now?

There are 4 equal glasses next to each other.
Each glass is filled with water to the same height.

One contains water & an egg
One contains water & paper clip
One contains water & a marble
One contains water & a rubber ball

Each object is immersed completely in the water of the respective glass.

Which glass contains most water?

I have six eggs

I broke two of them
I boiled two of them
I ate two of them.

How many do I have left?

I have 15 cows. They each give 20 liter of milk day.
Together, they eat up the grass from my pasture in 35 days.

For next season I want to increase my milk production to 500 liter per day. I buy cows like the ones I have, who give the same amount of milk and eat the same amount of grass...

How many days will it take the bigger herd to eat up the grass from my pasture?

I was assuming that you boiled and ate the ones you broke.
