In a kiosk that sells blazers, 600 silver blazers were sold and 10% of the remaining blazers that were sold were pink. Of the leftover, 50% of the blazers sold were gold blazers and the rest were white blazers. Given that the number of white blazers sold was 20% of the total number of blazers sold, how many pink and silver blazers were sold altogether?
10% = ¹⁰₁₀₀ = ¹₁₀
50% = ⁵⁰₁₀₀ = ¹₂
20% = ²⁰₁₀₀ = ¹₅

Silver	Pink	Gold	White
600	1x2	9x2
		1x9	1x9
4x9			1x9
25 u	2 u	9 u	9 u

The total number of gold and white shirts is the combined repeated identity. Make the total number of gold and white shirts the same. LCM of 9 and 2 is 18.

The number of white shirts is repeated. Make the number of white shirts the same. LCM of 9 and 1 is 9.

Number of silver blazers
= 36 u - 2 u - 9 u
= 25 u

25 u = 600

1 u = 600 ÷ 25 = 24

Number of pink and silver blazers
= 2 u + 600
= (2 x 24) + 600
= 48 + 600
= 648

Answer(s): 648
