Approximation Quiz Set for For SBI Clerk 2026
Q1. What approximate value should replace the question mark? 53.003 × 9.95 × (257.81 ÷ 6.01) − (45 × 5) = ?
Explanation: Use 53.003≈53, 9.95≈10, 257.81≈258, and 6.01≈6. Then 53×10×(258÷6)−225 = 530×43−225 = 22,565. The exact value is about 22,397.93, so B is also the closest listed option.
Q2. What approximate value should replace the question mark? 12.512% of 399.98 + 85.714% of 28.18 = ?
Explanation: 12.512%≈12.5%=1/8 and 399.98≈400, giving 50. Also 85.714%≈6/7 and 28.18≈28, giving 24. Total ≈74.
Q3. What approximate value should replace the question mark? √143.99 + 29.88 × 3.02 − 18.91 = ?
Explanation: √143.99≈√144=12, 29.88≈30, 3.02≈3, and 18.91≈19. Thus 12+30×3−19 = 83.
Q4. What approximate value should replace the question mark? 39.98 × 14.96 + 25.04 = ?
Explanation: 39.98≈40, 14.96≈15, and 25.04≈25. Therefore 40×15+25 = 625.
Q5. What approximate value should replace the question mark? (124.9 ÷ 4.98) + 18.9 = ?
Explanation: 124.9≈125, 4.98≈5, and 18.9≈19. Therefore 125÷5+19 = 25+19 = 44.
Q6. What approximate value should replace the question mark? 49.9% of 400.2 + 30.2 = ?
Explanation: 49.9%≈50%, 400.2≈400, and 30.2≈30. So 50% of 400 + 30 = 200+30 = 230.
Q7. What approximate value should replace the question mark? (15.1 × 20.1) − (9.8 × 5.1) = ?
Explanation: This item was minimally corrected from 20.2 to 20.1 to avoid a nearest-option tie/ambiguity. Approximate 15.1≈15, 20.1≈20, 9.8≈10, and 5.1≈5. Then 15×20−10×5 = 250. The exact value is about 253.53, which is also closer to 250 than 260.
Q8. What approximate value should replace the question mark? √1602 + 24.8 = ?
Explanation: √1602≈√1600=40 and 24.8≈25. Therefore 40+25 = 65.
Q9. What approximate value should replace the question mark? 49.8 × 20.1 ÷ 2.0 = ?
Explanation: 49.8≈50, 20.1≈20, and 2 remains 2. Thus 50×20÷2 = 500.
Q10. What approximate value should replace the question mark? 34.9 × 11.1 − 49.8 = ?
Explanation: Straight rounding gives about 35×11−50 = 335. Since 335 is not listed, compare with the nearby options. The actual value is 337.59, so 338 is clearly the closest option.

Solve More QuestionsKey Strategies to Solve Approximation Fast
To attempt approximation questions quickly and accurately, incorporate the following mental math techniques:
- Follow BODMAS Strictly: Always carry out calculations in the order of Brackets, Orders (powers and roots), Division, Multiplication, Addition, and Subtraction.
- Round Off Wisely: Decimal values like .98, .95, and .89 should be rounded up to the next whole number. Values like .01, .02, and .12 should be rounded down.
- Memorize Key Benchmark Values:
- Squares: Memorize up to 50 (e.g., 25 square = 625, 35 square = 1225).
- Cubes: Memorize up to 20 (e.g., 12 cube = 1728, 15 cube = 3375).
- Fraction to Percentage Conversions: Memorize up to 1/20 (e.g., 12.5% = 1/8, 85.71% = 6/7, 16.66% = 1/6).
- Avoid Exact Calculations: Never calculate exact long divisions or detailed decimal remainders. Compare your rounded work directly with the multiple-choice options.
