## How to solve a SSC CGL level tricky age ratio problem lightning fast

For quick solution of ratio proportion problems use multiple of ratio value technique. Here, a tricky age ratio problem is solved very fast to show how.

This is not specific to any exam. Each article highlights how difficult problems can be solved say in 3 steps instead of conventional 10 steps.

Under this section we will solve typical math problems that a **student might find difficult** when preparing for **competitive tests such as SSC CGL, CAT, GRE etc**. We will also cover Secondary school level or even occasionally Olympiad level problems.

The ** chief criteria** that will be common to the problems here will be three:

- The problem should not require too much math knowledge to solve,
- The problem should have an inherent difficulty for most of the students or may be too lengthy and,
- The problem must be solvable following an elegant method in a very short time.

We don't like to deal with laborious problems. Generally each of these problems can be solved in a number of ways.

As we teach ** efficient problem solving** as a subject, we will always try to

It means, each problem and its solution that we explain here **won't just be for that specific problem**. More importantly, the underlying concepts about how the solution was reached efficiently and in very quick time, form the most valuable treasure to be recognized and owned by the student **by understanding the concepts and applying the concepts in future problems.**

In profit and loss problems when price or profit changes by certain percentages, without calculating the actual changed values and just by using the change and its effect, solution can be achieved very fast. We would solve two problems on profit and loss to highlight the power of this technique...

We have already treated an interesting type of profit and loss problem with equal sale prices and equal profit and loss figures in two transactions. This session we will be solving such a problem with equal sale prices but with unequal profit and loss percentages very fast and in two ways. We will use basic and rich profit and loss concepts, fraction concepts and mathematical reasoning to achieve the speed and elegance...

The chosen problem in this session is awkward and if you attempt to solve it through conventional deductions, it would be tedious and time consuming. You may even lose your way in confusion. Instead, if you are able to identify useful patterns and apply mathematical reasoning, solution would take just a few tens of seconds...
