In a kiosk that sells sweaters, 360 silver sweaters were sold and 50% of the remaining sweaters that were sold were pink. Of the leftover, 60% of the sweaters sold were red sweaters and the rest were gold sweaters. Given that the number of gold sweaters sold was 5% of the total number of sweaters sold, how many pink and silver sweaters were sold altogether?
50% = ⁵⁰₁₀₀ = ¹₂
60% = ⁶⁰₁₀₀ = ³₅
5% = ⁵₁₀₀ = ¹₂₀

Silver	Pink	Red	Gold
360	1x5	1x5
		3x1	2x1
19x2			1x2
30 u	5 u	3 u	2 u

The total number of red and gold shirts is the combined repeated identity. Make the total number of red and gold shirts the same. LCM of 1 and 5 is 5.

The number of gold shirts is repeated. Make the number of gold shirts the same. LCM of 2 and 1 is 2.

Number of silver sweaters
= 38 u - 5 u - 3 u
= 30 u

30 u = 360

1 u = 360 ÷ 30 = 12

Number of pink and silver sweaters
= 5 u + 360
= (5 x 12) + 360
= 60 + 360
= 420

Answer(s): 420
