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.) [(9.06/1.98) + (1.05/4.96) + (2.98/4.12)] × 20.12 – 6.81 2 = ?Solution
ATQ, [(9.06/1.98) + (1.05/4.96) + (2.98/4.12)] × 20.12 – 6.812 = ? ? ~ [(9/2) + (1/5) + (3/4)] × 20 – 72 ? ~ [(9 × 10 + 1 × 4 + 3 × 5) ÷ 20] × 20 – 49 ? ~ [(90 + 4 + 15) ÷ 20] × 20 – 49 ? ~ (109/20) × 20 – 49 ? ~ 109 – 49 ? ~ 60
