Key Concepts to Master

To solve approximation questions quickly and accurately, focus on these concepts:

• BODMAS Rule: Follow the correct order of operations (Brackets, Orders, Division, Multiplication, Addition, Subtraction).

• Rounding Off: Round numbers to the nearest whole number, ten, or hundred as needed (e.g., 83.13 → 83).

• Percentages and Fractions: Remember common equivalents (e.g., 16.66% ≈ 1/6, 33.33% ≈ 1/3).

• Squares and Cubes: Memorize squares up to 40 and cubes up to 20 to quickly estimate roots.

Common Approximation Questions for SBI PO

1. Percentage-Based Questions

These test your ability to convert percentages into simple fractions or whole numbers.

Pattern: 44.99% of 799.85 + 33.34% of 899.91 =?

Approach:

• Round 44.99% to 45% and 799.85 to 800.

• Round 33.34% to 1/3 and 899.91 to 900.

• (0.45 × 800) + (1/3 × 900) = 360 + 300 = 660

2. Square Root and Cube Root Questions

Find the nearest perfect square or cube.

Pattern: √1443.92 + ∛1727.89 = ?

Approach:

• √1444 = 38 (38² = 1444)

• ∛1728 = 12 (12³ = 1728)

• 38 + 12 = 50

3. Decimal Questions Using BODMAS

These involve lengthy calculations with decimals.

Pattern: 14.95 × 8.04 ÷ 4.97 + 22.05 = ?

Approach:

• Simplify to: 15 × 8 ÷ 5 + 22

• Apply BODMAS: 15 × 1.6 + 22 = 24 + 22 = 46

4. Exponents (Powers)

Convert all terms to the same base to find the missing power.

Pattern: (2.01)^3 × (3.99)^2 ÷ 7.98 = 2^?

Approach:

• Simplify to: 2³ × 4² ÷ 8

• Convert to base 2: 2³ × (2²)² ÷ 2³

• 2³ × 2⁴ ÷ 2³ = 2⁴

• Missing power = 4

5. Fraction Multiplication

These look difficult but become easy after rounding.

Pattern: (4.99/11.02) × (21.98/14.95) × 74.91 =?

Approach:

• Simplify to: (5/11) × (22/15) × 75

• Cancel common terms: (5/15 × 22/11) × 75 = (1/3 × 2) × 75

• (2/3) × 75 = 50
