In a mall that sells jumpsuits, 460 grey jumpsuits were sold and 50% of the remaining jumpsuits that were sold were yellow. Of the leftover, 40% of the jumpsuits sold were brown jumpsuits and the rest were silver jumpsuits. Given that the number of silver jumpsuits sold was 10% of the total number of jumpsuits sold, how many yellow and grey jumpsuits were sold altogether?

The total number of brown and silver shirts is the combined repeated identity. Make the total number of brown and silver shirts the same. LCM of 1 and 5 is 5.
The number of silver shirts is repeated. Make the number of silver shirts the same. LCM of 3 and 1 is 3.
Number of grey jumpsuits
= 27 u - 5 u - 2 u
= 20 u
20 u = 460
1 u = 460 ÷ 50 = 23
Number of yellow and grey jumpsuits
= 5 u + 460
= 5 x 23 + 460
= 115 + 460
= 575
Answer(s): 575
