In a stall that sells windbreakers, 160 green windbreakers were sold and 25% of the remaining windbreakers that were sold were silver. Of the leftover, 60% of the windbreakers sold were pink windbreakers and the rest were black windbreakers. Given that the number of black windbreakers sold was 10% of the total number of windbreakers sold, how many silver and green windbreakers were sold altogether?

The total number of pink and black shirts is the combined repeated identity. Make the total number of pink and black shirts the same. LCM of 3 and 5 is 15.
The number of black shirts is repeated. Make the number of black shirts the same. LCM of 6 and 1 is 6.
Number of green windbreakers
= 54 u - 5 u - 9 u
= 40 u
40 u = 160
1 u = 160 ÷ 25 = 4
Number of silver and green windbreakers
= 5 u + 160
= 5 x 4 + 160
= 20 + 160
= 180
Answer(s): 180
