In a stall that sells blouses, 8820 gold blouses were sold and 10% of the remaining blouses that were sold were pink.

The total number of silver and white shirts is the combined repeated identity. Make the total number of silver and white shirts the same. LCM of 9 and 5 is 45.
The number of white shirts is repeated. Make the number of white shirts the same. LCM of 27 and 1 is 27.
Number of gold blouses
= 513 u - 5 u - 18 u
= 490 u
490 u = 8820
1 u = 8820 ÷ 490 = 18
Number of pink and white blouses
= 5 u + 27 u
= 32 u
= 32 x 18
= 576
Answer(s): 576
