In a kiosk that sells blazers, 60 black blazers were sold and 50% of the remaining blazers that were sold were brown. Of the leftover, 60% of the blazers sold were red blazers and the rest were silver blazers. Given that the number of silver blazers sold was 10% of the total number of blazers sold, how many brown and silver blazers were sold altogether?

The total number of red and silver shirts is the combined repeated identity. Make the total number of red and silver shirts the same. LCM of 1 and 5 is 5.
The number of silver shirts is repeated. Make the number of silver shirts the same. LCM of 2 and 1 is 2.
Number of black blazers
= 18 u - 5 u - 3 u
= 10 u
10 u = 60
1 u = 60 ÷ 10 = 6
Number of brown and silver blazers
= 5 u + 2 u
= 7 u
= 7 x 6
= 42
Answer(s): 42
