Quadratic Equation Questions for SBI Clerk Practice Set

Here are some Quadratic Equation Questions for SBI Clerk based on the common comparison pattern. Try solving them yourself before checking the answers.

Directions (Q1–Q10)Solve both quadratic equations and compare all possible values of x and y. Choose the relationship that is true for every possible pairing. Each correct response carries +2 marks and each incorrect response carries −0.5 marks.

Q1. I. x² − 7x + 12 = 0 II. y² − 9y + 20 = 0

Correct Answer: E) x ≤ y
Explanation: Equation I gives x = 3 or 4. Equation II gives y = 4 or 5. Every possible x value is less than or equal to every possible y value. Equality occurs when x=4 and y=4. Therefore x ≤ y.

Q2. I. x² − 11x + 30 = 0 II. y² − 13y + 42 = 0

Correct Answer: E) x ≤ y
Explanation: x = 5 or 6 and y = 6 or 7. In every pairing, x ≤ y, with equality possible at 6. Therefore x ≤ y.

Q3. I. x² + 9x + 20 = 0 II. y² + 11y + 30 = 0

Correct Answer: D) x ≥ y
Explanation: x = −4 or −5 and y = −5 or −6. Every possible x value is greater than or equal to every possible y value. Equality is possible at −5. Therefore x ≥ y.

Q4. I. x² − 15x + 56 = 0 II. y² − 17y + 72 = 0

Correct Answer: E) x ≤ y
Explanation: x = 7 or 8 and y = 8 or 9. Therefore every x value is less than or equal to every y value, so x ≤ y.

Q5. I. x² − 10x + 21 = 0 II. y² − 12y + 32 = 0

Correct Answer: C) x = y or relationship cannot be established
Explanation: x = 3 or 7 and y = 4 or 8. For x=3,y=4, x<y; but for x=7,y=4, x>y. Hence no single relationship holds for all combinations, so the relationship cannot be established.

Q6. I. 2x² − 14x + 24 = 0 II. y² − 9y + 20 = 0

Correct Answer: E) x ≤ y
Explanation: Dividing Equation I by 2 gives x²−7x+12=0, so x=3 or 4. Equation II gives y=4 or 5. Thus x ≤ y in every possible pairing.

Q7. I. x² + 5x + 6 = 0 II. y² + 7y + 12 = 0

Correct Answer: D) x ≥ y
Explanation: x = −2 or −3 and y = −3 or −4. Every x value is greater than or equal to every y value, with equality possible at −3. Therefore x ≥ y.

Q8. I. x² − 6x + 8 = 0 II. y² − 8y + 15 = 0

Correct Answer: C) x = y or relationship cannot be established
Explanation: x = 2 or 4 and y = 3 or 5. x can be less than y, for example 2<3, but it can also be greater than y, for example 4>3. Therefore the relationship cannot be established.

Q9. I. x² − 13x + 42 = 0 II. y² − 15y + 56 = 0

Correct Answer: E) x ≤ y
Explanation: x = 6 or 7 and y = 7 or 8. Every x value is less than or equal to every y value, with equality possible at 7. Therefore x ≤ y.

Q10. I. x² + 8x + 15 = 0 II. y² + 10y + 21 = 0

Correct Answer: C) x = y or relationship cannot be established
Explanation: x = −3 or −5 and y = −3 or −7. For x=−5,y=−3, x<y; but for x=−3,y=−7, x>y. Hence the relationship cannot be established.

Common Types of SBI Clerk Quadratic Equation Questions

The format is usually simple, but the numbers can be changed to test your speed. Quadratic Equation Questions for SBI Clerk mainly include the following types:

1. Factor-Based Questions

These are the easiest type. You can split the middle term and find the roots quickly.

2. Comparison of Two Equations

You solve Equation I and Equation II and then compare their roots. This is one of the most common formats for banking exams.

3. Equations With Different Coefficients

Sometimes the equations contain coefficients before x², x, or the constant term. In these questions, first bring the equation into the standard form: ax² + bx + c = 0. Then solve or factorise it.

4. Same or Overlapping Roots

Both equations may have one common root. In such cases, read the options carefully before marking x = y.

5. No Real Root Case

Some equations may not have real roots. If the question gives such an equation, you cannot compare x and y in the normal way. This is why checking the discriminant can sometimes be useful.

How to Solve SBI Clerk Quadratic Equation Questions Quickly?

The easiest way to solve most questions is factorisation. This method is much faster than using the quadratic formula when the numbers are easy to factor. For Quadratic Equation Questions for SBI Clerk, mastering factorisation can help you save valuable time and improve accuracy.

Suppose: x² – 9x + 20 = 0

Find two numbers whose:

Product = 20
Sum = -9

The numbers are -4 and -5.

Therefore: (x – 4)(x – 5) = 0

So: x = 4 or 5.

Quadratic Equation Shortcuts for SBI Clerk

Using quick shortcuts can help you solve questions faster and avoid calculation errors. These techniques are especially useful when attempting Quadratic Equation Questions for SBI Clerk under the exam’s time pressure.

1. Factorisation Shortcut

For: x² + bx + c = 0

look for two numbers whose:

Sum = b
Product = c

Then write the two factors.

2. Use the Discriminant When Needed

This can help when factorisation is difficult. For: ax² + bx + c = 0

the discriminant is: D = b² – 4ac

If:

D > 0 → Two real roots
D = 0 → One repeated real root
D < 0 → No real roots

3. Remember Root Relationships

These relationships can sometimes help you compare values without fully solving the equation. For: ax² + bx + c = 0

Sum of roots: -b/a

Product of roots: c/a

Benefits of Solving SBI Clerk Quadratic Equation Questions

Regular practice helps improve calculation speed, accuracy, and confidence in the Numerical Ability section. Solving Quadratic Equation Questions for SBI Clerk also helps you identify common patterns quickly and manage your exam time more effectively.

1. Improves Calculation Speed

Quadratic equations can be solved quickly when you become familiar with common factor pairs. Regular practice helps you recognise these patterns faster.

2. Builds Accuracy

Repeated practice helps reduce mistakes in signs, factorisation, and root comparison.

3. Helps With Question Selection

When you see a familiar quadratic equation in the exam, you can quickly decide whether to attempt it or move to another question.

4. Makes You Comfortable With Dual Equations

Many questions give one equation for x and another for y. Practising this format helps you compare roots without confusion.

5. Builds Confidence

Solving a large number of questions helps you understand which types are easy and which ones need more practice.

7-Day SBI Clerk Quadratic Equation Practice Plan

Follow a focused 7-day schedule to build speed, accuracy, and confidence in solving Quadratic Equation Questions for SBI Clerk. Dedicate a short practice session each day and gradually increase the difficulty.

Day	What to Practise
Day 1	Basic algebra and factorisation
Day 2	Simple quadratic equations
Day 3	x-y comparison questions
Day 4	Mixed-level questions
Day 5	Timed practice set
Day 6	Previous-year questions + error analysis
Day 7	Full revision + mock test

Final Thoughts

Quadratic Equation Questions for SBI Clerk can become a quick-scoring area when you practise the right question format regularly. Focus first on factorisation, then move to x-y comparison questions and timed mixed sets. Do not spend too much time on one difficult equation. Learn the basic method, practise daily, check your mistakes, and improve your speed step by step. A good target is to solve a small set every day and gradually reduce the time taken for each question.
