Percentage means “per hundred.” It represents a fraction out of 100. For example:
Understanding fraction-to-percentage conversions can help you solve questions quickly during the exam.
| Fraction | Percentage |
|---|---|
| 1/2 | 50% |
| 1/3 | 33.33% |
| 1/4 | 25% |
| 1/5 | 20% |
| 3/4 | 75% |
Memorizing these values can save a lot of time while solving questions in competitive exams.
Percentage questions in the exam are usually asked in the following formats:
These questions test your ability to calculate percentages directly.
Example:
Find 25% of 480.
Solution:
25% of 480 = (25/100) × 480 = 120
These questions involve calculating the change in values.
Example:
If the price of a product increases from ₹400 to ₹460, find the percentage increase.
Increase = 460 – 400 = 60
Percentage increase = (60/400) × 100 = 15%
These questions involve multiple increases or decreases.
Example:
A salary increases by 10% and then decreases by 5%. What is the overall change?
These types of questions require knowledge of successive percentage formulas.
Many arithmetic problems use percentages indirectly.
For example:
These problems test both conceptual understanding and calculation skills.
Percentage questions are among the most common in banking exams, and they often look simple but can consume time if you don’t prepare smartly. By following the right techniques, you can solve them faster and with greater accuracy. Here are some detailed tips to help you master this topic.
One of the fastest ways to save time is to learn fraction‑to‑percentage conversions by heart. For example, ( \frac{1}{2} = 50% ), ( \frac{1}{3} \approx 33.33% ), ( \frac{1}{4} = 25% ), ( \frac{3}{4} = 75% ), and so on. These conversions appear repeatedly in exam questions. If you can recall them instantly, you won’t waste time calculating during the test.
Speed is crucial in competitive exams. Work daily on mental math skills like multiplication tables, division tricks, and approximation methods. For instance, knowing that 12.5% is the same as one‑eighth helps you solve questions quickly. Regular practice of these techniques will make your calculations smoother and reduce silly mistakes.
Many aspirants try to memorize formulas without grasping the logic. This creates confusion when the question format changes. Instead, focus on understanding what a percentage really means—“per hundred.” Once you understand the concept, you can easily adapt it to profit‑loss, ratio, or data interpretation questions. Conceptual clarity ensures flexibility in problem‑solving.
Previous year papers are a goldmine. They show you the exact difficulty level and the types of percentage problems that appear in the exam. By solving them, you’ll notice recurring patterns, such as percentage increase/decrease, successive percentage changes, or percentage comparisons in DI sets. This builds familiarity and confidence.
Mock tests replicate the real exam environment. They train you to manage time, handle pressure, and apply shortcuts effectively. After each mock, analyze your mistakes and note where you spent extra time. This reflection helps you improve steadily. Remember, it’s not just about solving questions—it’s about solving them quickly and accurately under exam conditions.
Percentage is a scoring topic if approached smartly. By memorizing conversions, sharpening calculation speed, focusing on concepts, revising past papers, and practicing mocks, you can turn this section into a strength. With consistent practice, you’ll not only save time but also secure easy marks in the IDBI JAM Grade O exam.
