In a shop that sells coats, 525 yellow coats were sold and 25% of the remaining coats that were sold were pink. Of the leftover, 40% of the coats sold were red coats and the rest were green coats. Given that the number of green coats sold was 20% of the total number of coats sold, how many pink and yellow coats were sold altogether?

The total number of red and green shirts is the combined repeated identity. Make the total number of red and green shirts the same. LCM of 3 and 5 is 15.
The number of green shirts is repeated. Make the number of green shirts the same. LCM of 9 and 1 is 9.
Number of yellow coats
= 36 u - 5 u - 6 u
= 25 u
25 u = 525
1 u = 525 ÷ 25 = 21
Number of pink and yellow coats
= 5 u + 525
= 5 x 21 + 525
= 105 + 525
= 630
Answer(s): 630
