Lower primary school mathematics question LPQ85

During the school anniversary dinner event, there are 48 more guests lined up in Queue A than Queue B at the reception area. In order to speed up the receipting process, Sarin decided to transfer some guests in the queue. How many guests must be transferred from Queue A to Queue B so that there are 24 more guests in Queue A than Queue B?

Solution:

Draw the model

Finally, there are 24 more Guests in Queue A than Queue B

The number of guests in Queue A more than Queue B is 2 times (48) initially

From the model

1 unit of the 48 needs to transfer from Queue A to Queue B to have 24 guests more in Queue A

4 units = 48

1 unit = 12

12 guests need to transfer from Queue A to Queue B
