In a stall that sells jumpsuits, 550 blue jumpsuits were sold and 50% of the remaining jumpsuits that were sold were pink. Of the leftover, 40% of the jumpsuits sold were green jumpsuits and the rest were black jumpsuits. Given that the number of black jumpsuits sold was 5% of the total number of jumpsuits sold, how many pink and blue jumpsuits were sold altogether?
50% = ⁵⁰₁₀₀ = ¹₂
40% = ⁴⁰₁₀₀ = ²₅
5% = ⁵₁₀₀ = ¹₂₀

Blue	Pink	Green	Black
550	1x5	1x5
		2x1	3x1
19x3			1x3
50 u	5 u	2 u	3 u

The total number of green and black shirts is the combined repeated identity. Make the total number of green and black shirts the same. LCM of 1 and 5 is 5.

The number of black shirts is repeated. Make the number of black shirts the same. LCM of 3 and 1 is 3.

Number of blue jumpsuits
= 57 u - 5 u - 2 u
= 50 u

50 u = 550

1 u = 550 ÷ 50 = 11

Number of pink and blue jumpsuits
= 5 u + 550
= (5 x 11) + 550
= 55 + 550
= 605

Answer(s): 605
