<p>This is the <strong>second part</strong> of our Numerical Ability reviewer for the Civil Service Examination (CSE). In this section, we focus on <strong>more advanced problem-solving techniques</strong>, shortcuts, and commonly repeated question types.</p>

<p>If you already know the basics, this part will help you <strong>increase speed and accuracy</strong>—critical for passing the exam.</p>

<h2>Advanced Topics You Must Master</h2>

<h3>1. Percentage Increase and Decrease</h3>

<p><strong>Formula:</strong></p>
<p>Increase = Original × (1 + Rate)</p>
<p>Decrease = Original × (1 − Rate)</p>

<p><strong>Example:</strong><br />
A salary of 1,000 increases by 20%<br />
👉 New salary = 1,200</p>

<h3>2. Profit and Loss</h3>

<p><strong>Formulas:</strong></p>
<ul>
<li>Profit = Selling Price − Cost Price</li>
<li>Loss = Cost Price − Selling Price</li>
<li>Profit % = (Profit / Cost Price) × 100</li>
</ul>

<p><strong>Example:</strong><br />
Cost = 500, Sold = 600<br />
👉 Profit = 100 (20%)</p>

<h3>3. Simple Interest</h3>

<p><strong>Formula:</strong></p>
<p>SI = (Principal × Rate × Time) / 100</p>

<p><strong>Example:</strong><br />
P = 1,000, R = 5%, T = 2 years<br />
👉 SI = 100</p>

<h3>4. Speed, Distance, and Time</h3>

<p><strong>Formula:</strong></p>
<p>Distance = Speed × Time</p>

<p><strong>Shortcut Tip:</strong><br />
If speed doubles, time is cut in half.</p>

<h3>5. Work Problems</h3>

<p><strong>Formula:</strong></p>
<p>Work = Rate × Time</p>

<h2>Powerful Shortcuts for Faster Solving</h2>

<ul>
<li>25% = 1/4</li>
<li>50% = 1/2</li>
<li>75% = 3/4</li>
<li>10% = move decimal one place left</li>
</ul>

<p><strong>Example:</strong><br />
10% of 250 = 25 instantly</p>

<h2>Practice Questions (Advanced Level)</h2>

A. 20%<br />
B. 25%<br />
C. 30%<br />
D. 35%<br />
<strong>Answer: B. 25%</strong></p>

<p><strong>2. Find the simple interest: P = 2,000, R = 5%, T = 3 years</strong><br />
A. 200<br />
B. 250<br />
C. 300<br />
D. 350<br />
<strong>Answer: C. 300</strong></p>

<p><strong>3. A car travels 120 km in 3 hours. What is its speed?</strong><br />
A. 30 km/h<br />
B. 40 km/h<br />
C. 50 km/h<br />
D. 60 km/h<br />
<strong>Answer: B. 40 km/h</strong></p>

<p><strong>4. If a price decreases by 10% from 500, what is the new price?</strong><br />
A. 450<br />
B. 460<br />
C. 470<br />
D. 480<br />
<strong>Answer: A. 450</strong></p>

<p><strong>5. If 5 workers finish a job in 10 days, how many days will 10 workers take?</strong><br />
A. 2<br />
B. 5<br />
C. 8<br />
D. 10<br />
<strong>Answer: B. 5</strong></p>

<h2>Exam Strategy Tips</h2>

<ul>
<li>Use shortcuts instead of long solutions</li>
<li>Estimate answers when possible</li>
<li>Avoid overthinking simple questions</li>
<li>Practice under time pressure</li>
<li>Memorize common percentages and fractions</li>
</ul>

<h2>Final Thoughts</h2>

<p>Numerical Ability is one of the easiest sections to improve with practice. Mastering shortcuts and advanced problem types will give you a <strong>huge advantage</strong> during the exam.</p>

<p><strong>Consistency is key—practice daily and track your progress.</strong></p>
