In a shopping centre that sells jumpsuits, 880 gold jumpsuits were sold and 10% of the remaining jumpsuits that were sold were purple. Of the leftover, 60% of the jumpsuits sold were white jumpsuits and the rest were blue jumpsuits. Given that the number of blue jumpsuits sold was 20% of the total number of jumpsuits sold, how many purple and gold jumpsuits were sold altogether?
10% = ¹⁰₁₀₀ = ¹₁₀
60% = ⁶⁰₁₀₀ = ³₅
20% = ²⁰₁₀₀ = ¹₅

Gold	Purple	White	Blue
880	1x5	9x5
		3x9	2x9
4x18			1x18
40 u	5 u	27 u	18 u

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

The number of blue shirts is repeated. Make the number of blue shirts the same. LCM of 18 and 1 is 18.

Number of gold jumpsuits
= 72 u - 5 u - 27 u
= 40 u

40 u = 880

1 u = 880 ÷ 40 = 22

Number of purple and gold jumpsuits
= 5 u + 880
= (5 x 22) + 880
= 110 + 880
= 990

Answer(s): 990
