Ratio and Proportion Methods shortcut tricks
You all know that math portion is very much important in competitive exams. That doesn’t mean that other sections are not so important. But only math portion can leads you to a good score. A good score comes with practice and practice. All you need to do is to do math problems correctly within time, and only shortcut tricks can give you that success. But it doesn’t mean that without using shortcut tricks you can’t do any math problems. You may have that potential that you may do maths within time without using any shortcut tricks. But so many people can’t do this. Here we prepared ratio and proportion shortcut tricks for those people. Here in this page we try to put all types of shortcut tricks on Ratio and Proportion. But we may miss few of them. If you know anything else rather than this please do share with us. Your little help will help so many needy.
- What is Ratio?
A ratio is a relationship between two numbers by division of the same kind. The ration of a to b is written as a : b = a / b, In ratio a : b, we can say that a as the first term or antecedent and b the second term or consequent.
Example : The ratio 4 : 9 we can represent as 4 / 9 after this 4 is a antecedent and, consequent = 9
- Rule of ration : In ratio multiplication or division of each an every term of a ratio by the same non- zero number does not affect the ratio.
Different type of ratio problem are given in Quantitative Aptitude which is a very essential topic in banking exam. Under below given some more example for your better practice.
Anything we learn in our school days was basics and that is well enough for passing our school exams. Now the time has come to learn for our competitive exams. For this we need our basics but also we have to learn something new. That’s where shortcut tricks and formula are comes into action.
- What is Proportion?
The idea of proportions is that two ratios are like equal.
If a : b = c : d, we write a : b : : c : d,
Ex. 3 / 15 = 1 / 5
a and d called extremes, where as b and c called mean terms.
- Proportion of quantities
the four quantities like a, b, c, d we can say proportion then we can express it
a : b = c : d
Then a : b : : c : d <–> ( a x d ) = ( b x c )
product of means = product of extremes.
If there is given three quantities like a, d, c of same like then we can say it proportion of continued.
a : d = d : c , d is called mean term. a and c are called extremes.
