Best Maths Tricks and Shortcuts for the upcoming NIACL 2024 exam

Here are the best short cuts that can speed up your calculations in the exam:

1. Finding Square Roots

To find the square root of a number, estimate and multiply:

• Identify the digit in the one’s place.
• Check the squares of numbers with the same digit in the one’s place (e.g., 6 β 42 = 16, 62 = 36).
• Find the square of a number closest to the first two digits of the given number (e.g., 21).
• Multiply the two numbers obtained in the previous steps (e.g., 4 Γ 5 = 20).
• If the result is greater than 10, the square root will be the smaller number (e.g., 32).

2. Finding Cube Roots

To find the cube root of a number:

• Identify the digit in the one’s place (e.g., 1).
• Find the cube of numbers with the same digit (e.g., 1 Γ 1 Γ 1 = 1).
• Determine the first digit of the number (e.g., 9).
• The cube root lies between the cube of 2 (8) and 3 (27). Choose the closest value (e.g., 21).
• For more accuracy, multiply the chosen value by the next number in the series (e.g., 3 Γ 4 = 12).
• If the result is greater than 10, the cube root will be the smaller number (e.g., 32).

• Multiply the coefficient of xΒ² and the constant in the equation.
• Multiply “-1” with the coefficient of x.
• If both results are positive, the value of x will be positive; otherwise, it will be negative.

4. Number Series Patterns

• Find the difference between two numbers in the series.
• Observe if the pattern follows the square of numbers.
• Use this approach to decipher complex number series.

5. Time and Work

Time taken by three people working together:

• Time = (LCM) / (Efficiency of all three).

6. Compound Interest Formulas

If compound interest rates are x% and y% for equal time intervals:

• Total interest = x + y + (xy/100).

For different time intervals:

• A1 = Compound Interest for T years
• A2 = Compound Interest for 2T years
• Interest = A2 – A1
• Interest after T+1 years = A2 – A1.

7. Multiplication Shortcut

Multiply two numbers:

• Multiply the first number by the tens digit of the second number.
• Add a “0” to the result.
• Multiply the first number by the ones digit of the second number.
• Add the results from steps 2 and 3.

8. Rule of 72

• Used to double a sum of money at a given interest rate.
• Time duration to double the amount = 72 / interest rate (in percentage).

9. Mixture and Alligation

• Solve mixture problems using the concept of alligation.
• Refer to the linked article for detailed explanations and sample questions.

Remember that these tricks and shortcuts can be valuable when you have a strong foundation in the basics. Practice and understanding the context of each problem will enhance your problem-solving skills.
