2. Read the problems and solve.

(i) The weekly income of 4 brothers is 133.75, 135.50, 143.25 and 145.50. What is their average income?​

Step-by-step explanation:  

Given that income of 4 brothers is    

1st brother  income  Rs.133.75

2nd brother income  Rs.135.50

3rd brother income  Rs.143.25

4th brother income  Rs.145.50  

here we need to find  average of the their income

                        = (sum of the total incomes) / number of incomes

                        = (133.75+135.50+143.25+145.50)/ 4

                        = 558 / 4 = 139.5
