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?

12%

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%
