33 + x = 2 (9+x)
33 + x = 18 + 2x
33 + x - 2x = 18
33 - x = 18
x = 15

In 15 years (The mother will be 48 and the son 24).

"quadratic function" diophantus , a greek


Let x be Diophantus' age when he died.

His son died 4 years before Diophantus (so Diophantus was then x-4 years old). His son lived half as long as Diophantus so when he (son) died he was x/2.
Diophantus' son was born when Diophantus was (x-4)-x/2 years old. That was 5 years after his marriage so when Diophantus married he was (x-4)-x/2-5 years old. We also know that 1/6 of his life was spent in childhood, 1/12 in youth and 1/7 as bachelor so (x-4)-x/2-5=(1/6+1/12+1/7)x.
Now you solve last equation:
  • x-4-x/2-5=11/28x
  • x/2-11/28x=4+5
  • 3/28x=9
  • x=9*28/3=84 years

Diophantus was 84 years old when he died.

Father is 3 times as old as his daughter.In 12 years father will be 1 year less than twice his daugthers age.What is their age?


So the father is 3 times as old as his daughter.
Let F represent the age of the fatherLet D represet the age of the daughter
So we know from the first sentence,
F = 3 * D
From the second sentence, 12 years from now the father is 1 year les than twice his daughters age,
First, lets assume it's not 12 years from now (to avoid confusion), we would haveF + 1= 2 * D
But since its 12 years from now, we have to add 12 to both ages
(F + 12) + 1 = 2 * (D + 12)
Let's simplify a bit,

F + 13 = 2 * D + 24F = 2D + 11
Now we have to solve these two equations together, we can plug the first equation into the second,
F = 3 * DF = 2 * D + 11
3 * D = 2 * D + 11D = 11
So the daughter is 11 years old, we can find out how old the father is by plugging into the first equation
F = 3 * DF = 3 * 11F = 33
So the father is 33 and the daughter is 11.

Alvin is now 20 years older than his son.In 10 years,he will be twice as old as his son's age.What are their present age's?


Christine,
(D=Dad's age, and S=Son's age)

D=S+20 (Dad is 20 years older than Son)
D+10 = 2xS (In ten years Dad will be twice Son's current age)
therefore (by substitution):
S+20+10 = 2xS
S+30 = 2S
2S = S+30
2S-S = 30 (subtract S from both sides)
S = 30 (Son's current age) *answer*
D = S+20
D = 30+20
D = 50 (Dad's current age) *answer*

In ten years, Dad will be 60, which is twice Son's current age of 30.

Please ask for -Gort.

I tried to sign my 9 year old son in and I cant get "not ineligable to sign up" off my sign in page


At 9 years old he's too young. Granted you could work around that by signing him up under your name, but then your subjecting him to the dangers of the online world were everyone doesn't play fair. BE VERY CAUTIOUS.

Jasmin is twice as old as rodney nine years ago


Hi,

Let the present age of the Rodney = X
present Age of the Jasmin = Y

As per the Situation,

Y-9 = 2 (X - 9)
Y-9 = 2X - 18
Y = 2X - 18 +9
Y = 2X-9

Second,

X + Y = 45
Y = 45 - X

Taking Both the situations,

2X - 9 = 45 - X
3X = 54
X = 54/3 = 18

Y = 45 - 18 = 27

Hence,

Age of Jasmin = 27

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
