In a stall that sells shirts, 30 green shirts were sold and 25% of the remaining shirts that were sold were silver. Of the leftover, 60% of the shirts sold were white shirts and the rest were gold shirts. Given that the number of gold shirts sold was 20% of the total number of shirts sold, how many silver and green shirts were sold altogether?
25% =
25100 =
14 60% =
60100 =
35 20% =

The total number of white and gold shirts is the combined repeated identity. Make the total number of white and gold shirts the same. LCM of 3 and 5 is 15.
The number of gold shirts is repeated. Make the number of gold shirts the same. LCM of 6 and 1 is 6.
Number of green shirts
= 24 u - 5 u - 9 u
= 10 u
10 u = 30
1 u = 30 ÷ 25 = 3
Number of silver and green shirts
= 5 u + 30
= 5 x 3 + 30
= 15 + 30
= 45
Answer(s): 45
