Answer

⇒  Here, in given table we can see 1500−2000 has highest frequency 40.

∴   Modal class =1500−2000

⇒  So, l=1500,f1=40,f0=24,f2=33 and h=2000−1500=500

Mode=l+2f1−f0−f2f1−f0×h

            =1500+2(40)−24−3340−24×500

            =1500+80−5716×500

            =1500+2316×500

            =1500+347.826

            =1847.83

∴   Modal monthly expenditure of families is Rs.1847.83
