Here is another question in my child's mock paper:

Four brothers in a family share a pool of pocket money equally given by their parents every monday.One monday morning.Albert took his share from the drawer and left. Bernard not realising that Albert had taken his share,took his own share and left. Calvin also unaware that Albert and Berbard had taken their share , took his rightful share and left.David also un aware that the other three had taken their share, and he took his share and left. In the end , there was $81 left in the Drawer. How much money was there in the drawer at first?

Hi

Observe that that is a short line or tick at AE, FG and HG.This shows that the three lengths are the same which is 3 cm.
