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?

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
