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.) (13.66 × 29.21) + 21.78% of 598.34 = ? + 129.89Solution
ATQ,
((13.66 × 29.21) + 21.78% of 598.34 = ? + 129.89
(14 × 29) + 22% of 600 ~ ? + 130
406 + 0.22 × 600 – 130 ~ ?
? ~ 406 + 132 – 130
? ~ 408
