In a boutique that sells coats, 110 white coats were sold and 25% of the remaining coats that were sold were brown. Of the leftover, 50% of the coats sold were silver coats and the rest were yellow coats. Given that the number of yellow coats sold was 10% of the total number of coats sold, how many brown and white coats were sold altogether?
25% = ²⁵₁₀₀ = ¹₄
50% = ⁵⁰₁₀₀ = ¹₂
10% = ¹⁰₁₀₀ = ¹₁₀

White	Brown	Silver	Yellow
110	1x2	3x2
		1x3	1x3
9x3			1x3
22 u	2 u	3 u	3 u

The total number of silver and yellow shirts is the combined repeated identity. Make the total number of silver and yellow shirts the same. LCM of 3 and 2 is 6.

The number of yellow shirts is repeated. Make the number of yellow shirts the same. LCM of 3 and 1 is 3.

Number of white coats
= 27 u - 2 u - 3 u
= 22 u

22 u = 110

1 u = 110 ÷ 22 = 5

Number of brown and white coats
= 2 u + 110
= (2 x 5) + 110
= 10 + 110
= 120

Answer(s): 120
