How to Score 28+ Marks in LIC AAO Quant (Prelims)

The LIC Assistant Administrative Officer (AAO) exam is one of the most competitive insurance exams in India. While many aspirants clear the cut-off, very few manage to score high marks in Quantitative Aptitude, which is seen as the most time-consuming section of the Prelims. But, scoring 28+ marks out of 35 in Quant is absolutely possible if you follow the right preparation strategy, learn smart calculation techniques, and practice with real exam-level questions. In this blog, we will cover everything step by step, including important topics, formulas, tricks, time management, and exam-day hacks that will help you maximize your Quant score.

LIC AAO Prelims Quant Exam Pattern

Before jumping into strategies, let’s quickly look at the Quantitative Aptitude exam structure:

Section	No. of Questions	Marks	Time
Quantitative Aptitude	35	35	20 minutes

This means 1 question = 1 mark, and you get only 20 minutes. To score 28+, you need to attempt at least 30 questions with high accuracy.

Important Topics in LIC AAO Quant

Quantitative Aptitude in LIC AAO mainly revolves around the following topics:

1. Simplification & Approximation (5–7 Qs)
2. Number Series (Missing/Wrong) (5 Qs)
3. Data Interpretation (DI) – Tables, Bar Graphs, Line Graphs, Pie Charts, Caselets (10–12 Qs)
4. Arithmetic Word Problems – Time & Work, Profit & Loss, SI-CI, Partnership, Time-Speed-Distance, Averages, Ages, Ratio & Proportion, Probability, Mensuration, Mixtures (8–10 Qs)

To reach 28+ marks, you must master Simplification, Number Series, and DI, while also being strong in basic Arithmetic.

Topic-Wise Preparation Strategy For Scoring 28+ in Quant

Check the topic-wise strategy to score maximum in the Quant section of the LIC AAO Prelims 2025. We have covered the strategy for the four most important and most asked topics here. First is Simplification and Approximation. Second is Number Series. Third is Data Interpretation. And the last one is Arithmetic word problems.

Improve Speed in Simplification & Approximation

• Weightage: 5–7 marks
• This topic is generally considered easy and scoring. It can be solved within 10 to 15 seconds if you know tricks.
• Important Tricks:
  • Learn BODMAS rule (Bracket, Order, Division, Multiplication, Addition, Subtraction).
  • Memorize square roots (1–30) and cube roots (1–20).
  • Learn percentage-to-fraction conversions (e.g., 1/8 = 12.5%, 2/5 = 40%).
  • Practice approximation by rounding numbers (e.g., 298.9 is approximately 300).
    

Example Shortcut:
Q. 48.9 × 19.9 = ?
Instead of multiplying directly, round off: 49 × 20 = 980 (saves time).

Approach Number Series Questions Smartly

• Weightage: 5 marks
• Types: Missing series, Wrong number series.
• Patterns to Learn:
  • Multiplication/Division pattern
  • Difference pattern (+2, +6, +18, …)
  • Squares/Cubes involvement
  • Prime numbers involvement

Shortcut Approach:

• Check the difference between numbers first.
• If there is a greater gap between numbers, try multiplication or squares.
• If there is a smaller gap between the numbers, check addition/subtraction.

Solve Data Interpretation (DI) Sets

• Weightage: 10–12 marks (most crucial part).
• Types of DI in LIC AAO:
  • Tabular DI
  • Bar Graph / Line Graph
  • Pie Chart
  • Caselet DI (paragraph-based)
    

Strategy to Solve DI Quickly:

1. Read the question carefully before looking at the data.
2. Approximate where possible.
3. Use percentage shortcuts:
   • 10% of X = X/10
   • 25% of X = X/4
   • 12.5% of X = X/8
4. Memorize squares up to 30 & cubes up to 20 for faster calculations.

Example Trick:
If total students = 1200, Boys = 40%, Girls = ?
Girls = 100 – 40 = 60% of 1200 = 720 (done in seconds).

Practice More Arithmetic Word Problems

• Weightage: 8 to 10 marks
• Topics to Cover:
  
  • Ratio & Proportion
  • Percentages
  • Profit, Loss & Discount
  • Simple & Compound Interest
  • Time, Speed & Distance
  • Time & Work
  • Averages
  • Probability & Permutations
    

Formula Shortcuts:

• Simple Interest (SI) = (P × R × T)/100
• Compound Interest (CI) = P(1 + R/100)^T – P
• Speed, Distance, Time:  Speed = Distance/Time
• Work Formula: Work = Rate × Time
  

Example (Time & Work):
A can complete work in 12 days, B in 16 days. Together = ?
LCM(12,16) = 48
A = 4 units/day, B = 3 units/day – Together = 7 units/day
Total work = 48 -> 48/7 = 6.85 days

Shortcuts & Calculation Tricks For LIC AAO Quant

1. Multiplication Shortcuts
   • (a + b)(a – b) = a² – b²
   • (x + y)² = x² + 2xy + y²
2. Fraction to Percentage Conversions
   • 1/2 = 50%
   • 1/3 = 33.33%
   • 1/4 = 25%
   • 1/5 = 20%
   • 1/6 = 16.66%
     
3. Squares (1–50) & Cubes (1–30) Must be on fingertips.
4. Approximation: Round off big numbers for DI and Approximation.

Time Management Strategy (20 Minutes)

To score 28+, you must balance speed & accuracy. Below is the idea time split for Quant in LIC AAO Prelims.

• Simplification/Approximation: 4 mins (5–7 Qs)
• Number Series:  3 mins (5 Qs)
• DI: 7–8 mins (10–12 Qs)
• Arithmetic: 5–6 mins (8–10 Qs)

Attempt in this order: First secure easy marks (Simplification, Series), then DI, then Arithmetic.

Common Mistakes to Avoid in LIC AAO Quant

Below are the 4 common mistakes to avoid if you want to score 28+ marks in Quant in LIC AAO Prelims.

1. Spending too much time on one tough DI set.
2. Guessing without elimination leads to negative marking.
3. Ignoring Arithmetic basics (it can fetch 5–6 extra marks).
4. Not practicing with a timer causes mismanagement in exams.

Mock Tests & Analysis is the Key to Score 28+

The only way to consistently score high in Quant is through mock tests and analysis.

• Start with topic tests (5 to 10 mins) from PracticeMock Platform.
• Attempt full-length mocks from Mini mocks to simulate exam pressure.
• Use Banking Package (Pro, Plus, or Max) for in-depth solutions, PDFs, and practice.

 After every mock:

• Note down the questions you got wrong.
• Re-solve them the next day.
• Track your accuracy % (must be 85 to 90%+).
• With regular practice, your accuracy will increase in Quant.

Additional Tips to Ensure 28+ in Quant

Check the additional tips to ensure you get above 28 marks in the Quant section.

1. Target Easy Wins: Attempt Simplification & Series first.
2. Choose DI Wisely: If one set looks lengthy, skip and attempt the other.
3. Maintain 90% Accuracy: Avoid blind guesses.
4. Revise Formulas Daily: Keep a one-page formula sheet.
5. Stay Calm: A relaxed mind calculates faster.
