# Ratio And Proportion Questions – SSC, Bank, and Other Exams

Ratio and proportion is not just a topic of its own but this topic is seen in many topics of maths. Such as Time and Work, Profit and Loss, Simple Interest and Compound Interest, Average, Percentage, Mixture, and Allegation, etc.

Therefore, from the perspective of SSC, Bank, and Railways, this is a very important topic and many types of questions are also made on ratio and proportion.

##### What is the Ratio?

The numbers obtained by dividing any two numbers completely by a number are called ratio. For example, dividing 15:25 by 5 will give 3: 5, here 3: 5 is the final ratio because they cannot be divided by anyone number after that.

The ratio of two quantities P and Q is written as P: Q. Here, P is known as an antecedent, and Q is known as a
consequent. It can also be said that P: Q = kP: kQ, where k is any constant known as constant of proportionality, k ≠ 0.
Here P is 15 and Q is 25 and k is 5 that means kP:kQ = 5×3:5×5= 15:25.

Proportion – Multiplying any two ratios with each other is called proportion. Ex – 5/3 =15/9 = 5×9 = 3×15 =45:45 – 1 : 1
II Example – 8/3 = X/9 , 8×9 : 3 x X = 72 : 3X , X=72/3 = 24 X=24answer

Mean Proportion – a, b, and c are said to be in continued proportion if a/b: b/c

So, b2 = ac. Here, b is known as the mean proportion.

##### Problems on Ratio and Proportion

Many types of questions are formed on Ratio and Proportion such as

##### 1. Salary Based Questions

# The ratio of the incomes of Mr. Ajay Singh and Mr. Varun Sharma is 3:5 and the ratio of their expenses is 1:3. Who is saving more?

Solution- Income = Expenditure + Saving let 3:5 is 300: 500 means Ajay income is 300 and Varun income is 500 and their expenses is 1:2 means 100 and 200 then Ajay saving is 300 – 100 = 200 and Varun saving is 500 – 200 = 300

Varun saving is more than Ajay so answer is Varun.

##### 2. Questions Based on Age

# The age ratio of A and B is 5:11 and their sum is 96, then what is the age of A?
Solution – sum is 96 means 5x + 11x =96 , 16x = 96, x = 6
then the age of A is 5×6 = 30 and Age of B is 11×6= 66 and their sum is 30+66 = 96
Age of A is 30 answer.

##### 3. Questions Based on Coins and Money

# A box contains 1-rupee, 50-paise, and 25-paise coins in the ratio 8: 5 : 3. If the total amount of money in the box is 112.50, the number of 50-paise coins is

Solution – 1 rupess coin ratio is 8 so 1×8=8 rupees, 50 paise ratio is 5 convert in rupees means 50×5 = 2.50 rupees, 25 paise ratio is 3 means 25×3 = 0.75 rupees now, add all money = 8x+2.50x+0.75x = 11.25x which is equal to 112.50

11.25x= 112.50, x= 112.50/11.25= x= 10 tehn the number of 50 paise coins is 5x means 5×10= 50 answer.
