Question

among five people with income in rupee 15000 ,26000,16000,19000,50000 how many will have income less than the mean income of five people?

Answer 1

mean income =sum of all incomes/number of people
mean income= (15000+26000+16000+19000+50000)/5
mean income=126000/5=25200

only 15000, 16000 and 19000 are less than 252000, hence three people will have income less that the mean income of five people.

Answer 2

mean of income of five people =their total income/5
= 15,000+16,000+19,000 +26,000+50,000/5
= 126,000÷5
=25,200.
so three people have income less than mean.
