Question
(363.89% of 224.98 – 319.86% of 134.94) ÷ ? =
√(134.88 ÷ 15.25) 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.)Solution
ATQ, (363.89% of 224.98 – 319.86% of 134.94) ÷ ? = √(134.88 ÷ 15.25) (364% of 225 – 320% of 135) ÷ ? ~ √(135 ÷ 15) (3.64 × 225 – 3.20 × 135) ÷ ? ~ √9 3 × ? ~ 819 – 432 3 × ? ~ 387 ? ~ 387 ÷ 3 ? ~ 129
