In a mall that sells dresses, 200 pink dresses were sold and 25% of the remaining dresses that were sold were grey. Of the leftover, 40% of the dresses sold were yellow dresses and the rest were silver dresses. Given that the number of silver dresses sold was 20% of the total number of dresses sold, how many grey and silver dresses were sold altogether?

The total number of yellow and silver shirts is the combined repeated identity. Make the total number of yellow and silver shirts the same. LCM of 3 and 5 is 15.
The number of silver shirts is repeated. Make the number of silver shirts the same. LCM of 9 and 1 is 9.
Number of pink dresses
= 36 u - 5 u - 6 u
= 25 u
25 u = 200
1 u = 200 ÷ 25 = 8
Number of grey and silver dresses
= 5 u + 9 u
= 14 u
= 14 x 8
= 112
Answer(s): 112
