John is twice as old as Jane was when he was as old as she is now the sum of their ages is 63 How old are John and Jane?
John is 36, Jane is 27
When he was 27, she was 18.
The algebraic solution to the equation:
Let A = John and B = Jane, and time t = A - B (difference in ages)
If t years ago, John was twice as old
A = 2 (B - t) and substitute A - B for t
A = 2B - 2A + 2B
3A = 4B
A = 4/3 B
and since A + B = 63
4/3 B + B = 63
7/3 B = 63
B = 21 and A = 28

Xavier is twice as old as his sister Yolanda was when he was as old as she is now Their combined ages is 70 How old are they?
Okay, so let's make Xavier x, and Yolanda y. We know that their combined ages are 70, so: x + y = 70 Now, Xavier is twice as old as his sister Yolanda was when he was as old as she is now. To get how old Yolanda was when he was as old as she is now, we have how old she is now, minus the difference between their ages, which is y - (x - y). Xavier is twice as old as this, so: x = 2(y - (x - y)) Take out the second set of brackets: x = 2(y - x + y) which is: x = 2(2y - x) Multiply out the brackets: x = 4y - 2x Now, we know that x + y = 70 from the first equation, so: y = 70 - x replace y in the equation above (x = 4y - 2x) with 70 - x and you get: x = 4(70 - x) - 2x Multiply out the brackets again: x = 280 - 4x -2x x = 280 - 6x add 6x to both sides: 7x = 280 divide both sides by 7: x = 40 So Xavier is forty. Their combined ages are 70, so Yolanda is thirty.

The sum of the present ages of Vatha and Chris is 36 In 4 years time the sum of their ages will equal twice Vathas present age How old are they now?
Vatha is 22 years old. Chris is 16 years old. 36/2=18 + 4 years v = 22 v + c = 36 --> 22+ c = 36 --> c = 14

Does the name Jane come from France?
Not really. Jane in French is Jeanne; in the Middle Ages (as i Joan of Arc) the name was Jéhane, whicj developed into Joanne, Jane, Jean, Jeanette and so on. It is simply a feminine version of John/Jean/Sean/Jan/Ian. These all developed out of the Latin Johannes, which was taken over from the Greek version of the Hebrew Johanan. This was the original name of Saint John, after whom a large proportion of the world's population is now named.
Jane six years old is twice as old as her brother How old will Jane be when she is one and a half times as old as her brother?
Now: Jane is 6 and her brother is 3Later: Jane is 1.5x and her brother is xSo 1.5x - 6 = x - 3or .5x = 3and x = 6Her brother will be 6 and Jane will be 9.It's tricky!

Fred has 15 cows John has twice as many cows as fred had when fred had as many cows as John has now how many cows does John have?
Well, isn't that just a happy little puzzle! Let's break it down nice and easy. If Fred has 15 cows, and John has twice as many cows as Fred had when Fred had as many cows as John has now, John must have 30 cows. So John has 30 cows in this peaceful little scenario.
Abigail is now twice as old as Beth was when Abigail was as old as Beth is now When Beth is as old as Abigail is now the sum of their ages will be 63. How old are Abigail and Beth now?
Abigail will be 36 and Beth will be 27.Abigail is now 27 and Beth is 18.9 years ago, Abigail was 18 and Beth was 9 (twice her age)This is an algebra problem, and like most of them, the result turns out that the ratio of their ages is x to 0.75 x (the lower number being half of a half smaller).So for this question 7/4 x = 63 and x = 36
