Upper primary school mathematics question UPQ584

In the school anniversary event, Class 6A and Class 6B had to sell 480 dining tickets altogether. After Class 6A sold  3/4 of their share and Class 6B sold  5/8 of their share, each of the class had the same number of tickets left. How many tickets did Class 6B have to sell?

Solution:

Construction the model based on both classes have same number of tickets left finally. From the model,

20U = 480

1U = 24 tickets

The number of tickets Class 6B need to sell = 8 × 24 = 192

Alternative solution:

The unsold tickets are equal,

1/4 = 3/12  of Class 6A is equal to 3/8  of Class 6B

Total tickets = 480

Total in units = 12 + 8 = 20

20 units = 480

1 unit = 24 tickers

The number of tickets Class 6B need to sell = 8 × 24 = 192
