In an office, the data of employees in four different categories from three different cities B, C and D is given below in bar graph.
In which category is the difference between the numbers of employees from any two different cities maximum?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e 2.
Category 1:
B = 1600, C = 2000, D = 2500
Differences: 2000−1600=400, 2500−2000=500, 2500−1600=900 → Max = 900
Category 2:
B = 1750, C = 1800, D = 3000
Differences: 1800−1750=50, 3000−1800=1200, 3000−1750=1250 → Max = 1250
Category 3:
B = 1800, C = 2250, D = 2750
Differences: 2250−1800=450, 2750−2250=500, 2750−1800=950 → Max = 950
Category 4:
B = 2000, C = 2000, D = 2400
Differences: 2000−2000=0, 2400−2000=400, 2400−2000=400 → Max = 400
The maximum difference = 1250 in Category 2
