In a kiosk that sells dresses, 935 black dresses were sold and 10% of the remaining dresses that were sold were green. Of the leftover, 40% of the dresses sold were pink dresses and the rest were brown dresses. Given that the number of brown dresses sold was 20% of the total number of dresses sold, how many green and black dresses were sold altogether?
10% = ¹⁰₁₀₀ = ¹₁₀
40% = ⁴⁰₁₀₀ = ²₅
20% = ²⁰₁₀₀ = ¹₅

Black	Green	Pink	Brown
935	1x5	9x5
		2x9	3x9
4x27			1x27
85 u	5 u	18 u	27 u

The total number of pink and brown shirts is the combined repeated identity. Make the total number of pink and brown shirts the same. LCM of 9 and 5 is 45.

The number of brown shirts is repeated. Make the number of brown shirts the same. LCM of 27 and 1 is 27.

Number of black dresses
= 108 u - 5 u - 18 u
= 85 u

85 u = 935

1 u = 935 ÷ 85 = 11

Number of green and black dresses
= 5 u + 935
= (5 x 11) + 935
= 55 + 935
= 990

Answer(s): 990
