About Ratio and Proportion MCQs
This category includes all the standard ratio problems seen in aptitude tests. You will divide sums of money among people in a given proportion, update ratios after salary increments, compare boys and girls in a class, link chained ratios such as 5x = 3y and 5y = 3z, and solve shadow and speed problems using direct proportion. Questions also connect ratios with percentages, discounts, circle radii and areas, and simple probability.
Ratios are a building block for partnership, mixtures, time and work, and speed problems, so strong basics help across the whole quantitative section. Many questions can be solved in seconds by working with ratio units rather than actual values. Regular practice builds this habit and helps you avoid lengthy algebra in timed tests. Ratios also appear in geometry, map scales and recipe-style mixture questions.
Key facts to remember
- A ratio compares two quantities of the same kind by division.
- A proportion states that two ratios are equal, such as a:b = c:d.
- In a proportion a:b = c:d, the product ad equals the product bc.
- If the radius ratio of two circles is 1:3, their area ratio is 1:9.
- To divide an amount in the ratio a:b, give a/(a+b) and b/(a+b) of the total.

How to prepare for Ratio and Proportion MCQs
- Work in ratio units, for example treat 2:3 as 2k and 3k, to avoid long algebra in sharing and salary problems.
- For chained ratios, make the common term equal before combining, such as matching y in x:y and y:z.
- Remember that areas scale with the square and volumes with the cube of the length ratio.
- Check your answer by adding the parts back to the given total, a quick step that catches most errors.
Frequently asked questions
What is the difference between ratio and proportion?
A ratio compares two quantities, such as 2:3, showing how many times one contains the other. A proportion is a statement that two ratios are equal, such as 2:3 = 4:6. Proportions are used to find an unknown term when three are known.
How many Ratio and Proportion MCQs are on MCQs360?
MCQs360 has 81 Ratio and Proportion MCQs, and each one displays its answer instantly. They are free to practise without sign-up, so you can drill this topic regularly to improve speed. Begin with sharing problems before chained ratio questions.
Which exams ask Ratio and Proportion MCQs?
Ratio questions appear in NTS, ECAT, GAT, ISSB and public service commission tests in Pakistan. In India they are standard in SSC CGL, SSC CHSL, IBPS, SBI and RRB exams, and in Bangladesh in BCS and bank job tests.
How do you divide money in a given ratio?
Add the ratio parts to find the total number of parts, divide the amount by this total to get the value of one part, then multiply by each person's share. For Rs. 1,000 in the ratio 2:3, one part is 200, giving 400 and 600.
