Question 1148550
p = value of kelvin's property.
w = his wife's share.
s = his son's share.
d = his daughter's share.


w/s = 5/3
s/d = 4/3
w = d + 561000
p = w + s + d


in s/d = 4/3, solve for s to get s = 4d/3.


in w/s = 5/3, replace s with (4d/3) to get w/(4d/3) = 5/3
cross multiply to get 3w = 4(4d/3)
simplify to get 3w = 16d/3
divide both sides of this equation by 3 to get:
w = 16d/9


in w = d + 561000, replace w with 16d/9 to get:
16d/9 = d + 561000
multiply both sides of this equation by 9 to get:
16d = 9d + 5049000
subtract 9d from both sides of this equation to get:
11d = 5049000
solve for d to get:
d = 5049000 / 11 = 459000


since w = d + 591000, solve for w to get w = 1020000


since s/d = 4/3, replace d with 459000 to get:
s/d = s/459000 = 4/3
cross multiply to get 3s = 4*459000
solve for s to get s = 4*459000/3 = 612000


you have:
w = 1020000
s = 612000
d = 459000

p = w + s + d = 1020000 + 612000 + 459000 = 2091000


that's your answer.
the value of kelvin's property is 2,091,000.
his wife's share is 1,020,000.
his son's share is 612,000
his daughter's share is 459,000


the ratio of his wife's share to his son's share is equal to 5/3 = 1.6666.....
1020000/612000 = 1.6666...
they're the same, so the ratio is correct.


the ratio of his son's share to his daughter's share is 4/3 = 1.3333.....
612000/459000 = 1.333....
the're the same, so the ratio is correct.


his wife's share is 561000 more than his daughter's share.
459000 + 561000 = 1020000, so that's also correct.


add up his wife's share and his son's share and his daughter's share and your solution is that the value of kelvin's property is 2,091,000, as stated above.
