In a mall that sells blouses, 264 grey blouses were sold and 10% of the remaining blouses that were sold were brown. Of the leftover, 60% of the blouses sold were red blouses and the rest were blue blouses. Given that the number of blue blouses sold was 25% of the total number of blouses sold, how many brown and blue blouses were sold altogether?

The total number of red and blue shirts is the combined repeated identity. Make the total number of red and blue shirts the same. LCM of 9 and 5 is 45.
The number of blue shirts is repeated. Make the number of blue shirts the same. LCM of 18 and 1 is 18.
Number of grey blouses
= 54 u - 5 u - 27 u
= 22 u
22 u = 264
1 u = 264 ÷ 22 = 12
Number of brown and blue blouses
= 5 u + 18 u
= 23 u
= 23 x 12
= 276
Answer(s): 276
