What approximate value will come in place of question mark (?) in the following questions? (You are not expected to calculate the exact value)
Correct Answer :
534
Solution :
We are asked to find the approximate value that replaces the question mark (?) in the expression
We solve for ? by moving the last term to the right‑hand side:
? = (22.02² + (1⁄9)·44) + 45.09 % of 100.9
1. Compute 22.02²
22.02² = (22 + 0.02)² = 22² + 2·22·0.02 + 0.02² = 484 + 0.88 + 0.0004 = 484.8804
2. Compute one‑ninth of 44
⅟9 · 44 = 44⁄9 ≈ 4.8889
3. Add the two results
484.8804 + 4.8889 ≈ 489.7693
4. Compute 45.09 % of 100.9
45.09 % = 0.4509
0.4509 · 100.9 = 0.4509·100 + 0.4509·0.9 = 45.09 + 0.40581 ≈ 45.4958
5. Add this percentage value to the sum from step 3
489.7693 + 45.4958 ≈ 535.2651
6. Choose the closest option
The options are 534, 450, 239, 670. The value 535.3 is nearest to **534**, so the approximate answer is 534.
