Seth had to paint some containers. On the first day, the number of containers he painted was 10% of the number of containers that he had not painted. One week later, he painted another 306 containers. As a result, the total number of painted containers became 26 more than ³₅ of the total number of containers. How many more containers were unpainted than painted on the first day?

	Painted	Not painted	Total
Before	1x5 = 5 u	10x5 = 50 u	11x5 = 55 u
Change	+ 306	- 306
After	5 u + 306	50 u - 306	55 u
Comparing painted and not painted containers in the end	3x11 + 26 = 33 u + 26	2x11 - 26 = 22 u - 26	5x11 = 55 u

10% = ¹⁰₁₀₀ = ¹₁₀
Painted : Not painted = 1 : 10

The total number of containers remains unchanged. Make the total number of containers at first and in the end the same.  LCM of 11 and 5 is 55.

The number of containers painted in the end is repeated.

33 u + 26 = 5 u + 306
33 u - 5 u = 306 - 26
28 u = 280

1 u = 280 ÷ 28 = 10

Number of more containers that were not painted than painted on the first day
= 50 u - 5 u
= 45 u
= 45 x 10
= 450

Answer(s): 450
