Luke 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 103 containers. As a result, the total number of painted containers became 25 more than ⁴₅ of the total number of containers. How many less containers were painted than unpainted on the first day?

	Painted	Not painted	Total
Before	1x5 = 5 u	10x5 = 50 u	11x5 = 55 u
Change	+ 103	- 103
After	5 u + 103	50 u - 103	55 u
Comparing painted and not painted containers in the end	4x11 + 25 = 44 u + 25	1x11 - 25 = 11 u - 25	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.

44 u + 25 = 5 u + 103
44 u - 5 u = 103 - 25
39 u = 78

1 u = 78 ÷ 39 = 2

Number of less containers that were painted than not painted on the first day
= 50 u - 5 u
= 45 u
= 45 x 2
= 90

Answer(s): 90
