In a shop that sells coats, 4 silver coats were sold and 50% of the remaining coats that were sold were pink. Of the leftover, 40% of the coats sold were black coats and the rest were white coats. Given that the number of white coats sold was 25% of the total number of coats sold, how many pink and white coats were sold altogether?
50% =
50100 =
12 40% =

The total number of black and white shirts is the combined repeated identity. Make the total number of black and white shirts the same. LCM of 1 and 5 is 5.
The number of white shirts is repeated. Make the number of white shirts the same. LCM of 3 and 1 is 3.
Number of silver coats
= 9 u - 5 u - 2 u
= 2 u
2 u = 4
1 u = 4 ÷ 2 = 2
Number of pink and white coats
= 5 u + 3 u
= 8 u
= 8 x 2
= 16
Answer(s): 16
