The following histogram represents the distribution of total household expenditure (in ₹) of 200 manual workers in a city.
The number of workers whose total expenditure is ₹350 and above is what percentage less than the number of workers whose total expenditure is less than ₹250?
Answer & explanation
Correct answer: option 2
Number of workers with total expenditure is ₹350 and above = 40 + 16 + 10 =66
Number of workers whose total expenditure is less than ₹250 = 20 + 40 + 15 = 75
Required percentage = \(\frac{75-66 }{75}\) × 100
= \(\frac{9 }{3}\) × 4
= 12%
