In a shop that sells windbreakers, 340 gold windbreakers were sold and 50% of the remaining windbreakers that were sold were brown. Of the leftover, 40% of the windbreakers sold were pink windbreakers and the rest were yellow windbreakers. Given that the number of yellow windbreakers sold was 10% of the total number of windbreakers sold, how many brown and yellow windbreakers were sold altogether?

The total number of pink and yellow shirts is the combined repeated identity. Make the total number of pink and yellow shirts the same. LCM of 1 and 5 is 5.
The number of yellow shirts is repeated. Make the number of yellow shirts the same. LCM of 3 and 1 is 3.
Number of gold windbreakers
= 27 u - 5 u - 2 u
= 20 u
20 u = 340
1 u = 340 ÷ 20 = 17
Number of brown and yellow windbreakers
= 5 u + 3 u
= 8 u
= 8 x 17
= 136
Answer(s): 136
