Question
Office A has 1250 employees, of
which 44% are boys, and the remaining are girls. Office B has 12% more employees than Office A. In Office B, 54% of the total employees are girls. What percentage of the number of girls in Office A is represented by the number of girls in Office B?Solution
ATQ, Number of girls in Office ‘A’ = 1250 × (1 – 0.44) = 700 Total number of employees in office ‘B’ = 1250 × 1.12 = 1400 Number of girls in office ‘B’ = 1400 × 0.54 = 756 So, required % = (756/700) × 100 = 108% Alternate Solution Let total number of employees in office ‘A’ = 100x Number of girls in office ‘A’ = 0.56 × 100x = 56x Total number of employees in office ‘B’ = 1.12 × 100x = 112x Number of girls in office ‘B’ = 0.54 × 112x = 60.48x Required percentage = (60.48x/56x) × 100 = 108%
The Newton-Raphson method is an iterative technique primarily used for:
Which type of data can be ordered, but the differences between values are not meaningful (e.g., satisfaction ratings: "Good," "Better," "Best")?
The "standard deviation" is the square root of which other statistical measure?
In numerical computing, what type of error occurs when a continuous function is approximated by a discrete sum or a finite number of terms?
Which numerical method approximates the definite integral of a function by dividing the area under the curve into trapezoids?
What does a p-value less than a significance level (e.g., 0.05) typically indicate in hypothesis testing?
Which statistical measure quantifies the average squared deviation of each data point from the mean?
