In a stall that sells coats, 28 gold coats were sold and 50% of the remaining coats that were sold were purple. Of the leftover, 40% of the coats sold were green coats and the rest were blue coats. Given that the number of blue coats sold was 25% of the total number of coats sold, how many purple and blue coats were sold altogether?
50% =
50100 =
12 40% =
40100 =
25 25% =
25100 =

The total number of green and blue shirts is the combined repeated identity. Make the total number of green and blue shirts the same. LCM of 1 and 5 is 5.
The number of blue shirts is repeated. Make the number of blue shirts the same. LCM of 3 and 1 is 3.
Number of gold coats
= 9 u - 5 u - 2 u
= 2 u
2 u = 28
1 u = 28 ÷ 2 = 14
Number of purple and blue coats
= 5 u + 3 u
= 8 u
= 8 x 14
= 112
Answer(s): 112
