In a kiosk that sells dresses, 50 brown dresses were sold and 50% of the remaining dresses that were sold were white. Of the leftover, 40% of the dresses sold were green dresses and the rest were silver dresses. Given that the number of silver dresses sold was 25% of the total number of dresses sold, how many white and silver dresses were sold altogether?

The total number of green and silver shirts is the combined repeated identity. Make the total number of green and silver shirts the same. LCM of 1 and 5 is 5.
The number of silver shirts is repeated. Make the number of silver shirts the same. LCM of 3 and 1 is 3.
Number of brown dresses
= 9 u - 5 u - 2 u
= 2 u
2 u = 50
1 u = 50 ÷ 2 = 25
Number of white and silver dresses
= 5 u + 3 u
= 8 u
= 8 x 25
= 200
Answer(s): 200
