In a stall that sells jumpsuits, 40 silver jumpsuits were sold and 50% of the remaining jumpsuits that were sold were green. Of the leftover, 40% of the jumpsuits sold were black jumpsuits and the rest were grey jumpsuits. Given that the number of grey jumpsuits sold was 20% of the total number of jumpsuits sold, how many green and silver jumpsuits were sold altogether?

The total number of black and grey shirts is the combined repeated identity. Make the total number of black and grey shirts the same. LCM of 1 and 5 is 5.
The number of grey shirts is repeated. Make the number of grey shirts the same. LCM of 3 and 1 is 3.
Number of silver jumpsuits
= 12 u - 5 u - 2 u
= 5 u
5 u = 40
1 u = 40 ÷ 50 = 8
Number of green and silver jumpsuits
= 5 u + 40
= 5 x 8 + 40
= 40 + 40
= 80
Answer(s): 80
