The numbers born duringfor each
day of the period x

The numbers dead for each
day of the period y

Then
7x-7y=700
7x:7y::6:1

42y=7x
x=42y ÷ 7

Influents into Age 1 = x
Remanets of Age 1 = 67
Remanets of Age 2 46
Influents into Age 2 y
Decrementalists of Age 1 =
Decrementalists of Age 2 d

Then

x=67+
y=46 + d

x:y ::

D= x-67
d= y-46
x:y::67+D:46+d
46x+dx=67y+Dy
46x+x=47x=67y+Dy
47=xd/67
