In a shop that sells jackets, 308 gold jackets were sold and 25% of the remaining jackets that were sold were blue. Of the leftover, 50% of the jackets sold were brown jackets and the rest were white jackets. Given that the number of white jackets sold was 10% of the total number of jackets sold, how many blue and white jackets were sold altogether?

The total number of brown and white shirts is the combined repeated identity. Make the total number of brown and white shirts the same. LCM of 3 and 2 is 6.
The number of white shirts is repeated. Make the number of white shirts the same. LCM of 3 and 1 is 3.
Number of gold jackets
= 27 u - 2 u - 3 u
= 22 u
22 u = 308
1 u = 308 ÷ 22 = 14
Number of blue and white jackets
= 2 u + 3 u
= 5 u
= 5 x 14
= 70
Answer(s): 70
