Problem Solving - How old are we?

      How Old Are We?
I am twice my brother's age and one-fifth my mother's age.
My dad is older than mum by half my brother's age. All our ages are whole numbers.
  
I go to school but my brother doesn't, yet.

How old are we?
Is there more than one solution?

Extension:
Can you create your own ‘How old are we?’ question for your class maths mate, your parents, or your teacher?

Problem Solving - Vehicles in the Car Park

Vehicles in the Carpark

In the staff carpark there were only 12 vehicles, but 40 wheels.

What type of vehicles, and how many of them, might have been in the carpark?


Are there other possible solutions using different vehicles?
