Question
What approximate value will come in place of the question
mark (?) in the following question? (Note: You are not expected to calculate the exact value.) ? = {(120.49 – 58.46) + (39.57 – 24.52)} × 2.97Solution
ATQ,
? = {(120.49 – 58.46) + (39.57 – 24.52)} × 2.97
? ~ {(120 – 58) + (40 – 25)} × 3
? ~ (62 + 15) × 3
? ~ 77 × 3
? ~ 231
47.87% of 749.76 + 35.11% of 399.76 = √? + 23.15 × 20.87
