Answer:

Rs. 14850

Step-by-step explanation:

Let total income of Prachi's family = x

Earning Members of Prachi's family = 4

Given average income is = 18,564.50

ATQ: x/4=18564.50

=> x=74258

:.Total income of family was of Rs74258

When uncle started earning:

Total earning Members = (4+1) = 5

ATQ: x/5=17821.60

=> x= 89108

:. Present total income is of Rs. 89108

Thus, Prachi's uncle earn in a month = Rs. (89108 - 74258) = Rs. 14850

Answer:

Let the total income of 4 members of the family be x

so avg income = x/4= 18564.50

x= 4 x 18564.50 x 4= 74258

when his uncle starts earning, the number of members is 5

so avg income = x/5= 17281.60

x= 17281.60 x 5= 86408

difference in  total earning= 86408- 74258=Rs 12150

his uncle's earning= Rs 12150
