LPQ100-1

From the model,

1 unit = 243

Total = 10 × 243 + 392 = 2822

The number of people in the concert hall was 2822

Alternative solution:

The number of women in the concert hall = 243

The number of men in the concert hall = 4 × 243 = 972

The number of children in the concert hall = 243 + 972 + 392 = 1607

The total number of people in the concert hall = 1607 + 243 + 972 = 2822
