Question
299.78% of 40.14 - 150.04% of 59.85 + 249.89% of ? =
229.09 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;
299.78% of 40.14 - 150.04% of 59.85 + 249.89% of ? = 229.09
300% of 40 - 150% of 60 + 250% of ? ~ 230
(3 X 40) - (1.5 X 60) + (2.5 X ?) ~ 230
120 - 90 + (2.5 X ?) ~ 230
(2.5 X ?) ~ 230 - 30
(2.5 X ?) ~ 200
? ~ 80
