The following histogram represents the distribution of total household expenditure (in Rs.) of 200 manual workers in a city.
The number of workers whose total expenditure is Rs. 350 and above is what percentage less than the number of workers whose total expenditure is less than Rs. 250?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 12%.
The number worker whose expenses is between 100 to 150 = 20
The number worker whose expenses is between 150 to 200 = 40
The number worker whose expenses is between 200 to 250 = 15
Total of them = 20 + 40 + 15 = 75
The number worker whose expenses is between 350 to 400 = 40
The number worker whose expenses is between 400 to 450 = 16
The number worker whose expenses is between 450 to 500 = 10
Total of them = 40 + 16 + 10 = 66
Difference = 75 - 66 = 9
Difference % = 9/75 × 100 = 12%
