The ratio of the number of chickens in Farm P to the number of chickens in Farm Q was 5 : 7. There were 56 more chickens in Farm Q than in Farm P. When 8 chickens escaped from Farm Q, the farmer in Farm Q bought another 18 chickens. What was the new ratio of the number of chickens in Farm P to the number of chickens in Farm Q in the end? Give your answer in the simplest form.

	Farm P	Farm Q
Before	5 u	7 u
Change 1		- 8
Change 2		+ 18
After	5 u	7 u + 10

Number of more chickens in Farm Q than Farm P
= 7 u - 5 u
= 2 u

2 u = 56

1 u = 56 ÷ 2 = 28

Number of chickens in Farm P
= 5 u
= 28 x 5
= 140

Number of chickens in Farm Q
= 7 u
= 28 x 7
= 196

New number of chickens in Farm Q
= 7 u + 10
= 196 + 10
= 206

Farm P : Farm Q
140 : 206 _{(÷ 2)}
70 : 103

Answer(s): 70 : 103
