The histogram shows the number of employees of a factory in different classes of daily wages (in Rs).
The total number of employees whose daily wages are Rs 600 or more is what percentage more than the total number of employees whose daily wages are less than Rs 500?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 20%
Each group is the sum of its class bars; "what percentage more" divides the difference by the smaller group, which is the base of comparison.
Rs 600 or more: classes 600-650 and 650-700, \(55+35=90\)
Less than Rs 500: classes 400-450 and 450-500, \(30+45=75\)
Percentage more \(\displaystyle=\frac{90-75}{75}\times100=\frac{15}{75}\times100=20\%\)
