Essential Math Tricks for Competitive Exams

1. Multiplying Two-Digit Numbers Ending with 5

To square numbers ending with 5:

• Example: 25225^2252

  • Multiply the tens digit (2) by its next number (3): $2\times 3=6$

  • Append 25: $625$WIREDLeverage Edu

This method simplifies squaring numbers like 35, 45, etc.

2. Quick Percentage Calculations

To find 5% of a number:

• Example: 5% of 685

  • Move the decimal one place left: 68.5

  • Divide by 2: $68.5÷2=34.25$

This approach is useful for calculating discounts, interest rates, etc.

3. Multiplying Numbers with Same Tens Digit and Units Digit Adding to 10

For numbers like 42 and 48:

• Multiply the tens digit (4) by its next number (5): $4\times 5=20$

• Multiply the units digits: $2\times 8=16$

• Combine: $2016$Leverage Edu

This trick speeds up multiplication of such number pairs.

4. Divisibility Rules

• Divisible by 9: If the sum of digits is divisible by 9.

  • Example: 738 → $7+3+8=18$, and 18 is divisible by 9.Leverage Edu

• Divisible by 4: If the last two digits form a number divisible by 4.

  • Example: 316 → 16 is divisible by 4.Leverage Edu

These rules help quickly identify factors without full division.

5. Fast Addition Using Rounding

To add numbers like 48 and 77:

• Round 48 to 50 and 77 to 80: $50+80=130$

• Subtract the excess: $130-(2+3)=125$

This method simplifies mental addition by using round numbers.
