What is the between A’s age 4 years hence and B’s age 4 years ago?

Solution: You may find this question a bit confusing coz of its language. Just read the question and form equations using the information given like this.

Now, 4 years ago the ratio between A’s age and B’s age 4 years hence is 1:1. But we need to calculate the ratio between A and B such that (5x 4) :(3x – 4) I hope, your concept would have been cleared and you now evolve better understanding about it and will be able to solve questions on your own.

The age of A 4 years ago would be 5x – 4 and age of B 4 years from now will be 3x 4. The above given combinations are just few types, there could many like that, you will get better hold of it if you practice them.

It’s been given the ratio between the present age of A and B is 5:3.

Thus, their present age would be 5x and 3x respectively.For further information, including about cookie settings, please read our Cookie Policy .By continuing to use this site, you consent to the use of cookies. Write one of the equations so it is in the style "variable = ...": We can subtract x from both sides of x y = 8 to get y = 8 − x. Write one of the equations so it is in the style "variable = ...": Let's choose the last equation and the variable z: First, eliminate x from 2nd and 3rd equation. Well, we can see where they cross, so it is already solved graphically. Let's use the second equation and the variable "y" (it looks the simplest equation). Now repeat the process, but just for the last 2 equations.Related Topics: More Algebra Word Problems How to solve Age Problems Involving A Single Person?
