In a kiosk that sells dresses, 1360 white dresses were sold and 10% of the remaining dresses that were sold were brown. Of the leftover, 40% of the dresses sold were silver dresses and the rest were pink dresses. Given that the number of pink dresses sold was 20% of the total number of dresses sold, how many brown and pink dresses were sold altogether?

The total number of silver and pink shirts is the combined repeated identity. Make the total number of silver and pink shirts the same. LCM of 9 and 5 is 45.
The number of pink shirts is repeated. Make the number of pink shirts the same. LCM of 27 and 1 is 27.
Number of white dresses
= 108 u - 5 u - 18 u
= 85 u
85 u = 1360
1 u = 1360 ÷ 85 = 16
Number of brown and pink dresses
= 5 u + 27 u
= 32 u
= 32 x 16
= 512
Answer(s): 512
