In a boutique that sells blouses, 280 yellow blouses were sold and 10% of the remaining blouses that were sold were white. Of the leftover, 60% of the blouses sold were green blouses and the rest were pink blouses. Given that the number of pink blouses sold was 20% of the total number of blouses sold, how many white and pink blouses were sold altogether?

The total number of green and pink shirts is the combined repeated identity. Make the total number of green and pink shirts the same. LCM of 9 and 5 is 45.
The number of pink shirts is repeated. Make the number of pink shirts the same. LCM of 18 and 1 is 18.
Number of yellow blouses
= 72 u - 5 u - 27 u
= 40 u
40 u = 280
1 u = 280 ÷ 40 = 7
Number of white and pink blouses
= 5 u + 18 u
= 23 u
= 23 x 7
= 161
Answer(s): 161
