Question
8.15 of 124.95 ÷ 40.13 + 249.84 X 14.18 - √325 X
149.87 = ? X 10.85 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, 8.15 of 124.95 ÷ 40.13 + 249.84 X 14.18 - √325 X 149.87 = ? X 10.85 Or, 8 of 125 ÷ 40 + 250 X 14 - √324 X 150 ~ ? X 11 Or, 1000 ÷ 40 + 3500 - 18 X 150 ~ ? X 11 Or, 25 + 3500 - 2700 ~ ? X 11 Or, ? ~ (825/11) So, ? ~ 75
