The monthly expenditure of a family on various items is represented in a pie chart where expenditures are given in percentages. If the difference in expenditure between education (18%) and travel (8%) is Rs. 4,000, then what is the total income of the family?
- ARs. 50,000
- BRs. 40,000
- CRs. 60,000
- DRs. 30,000
Solution & Step-by-step Explanation
Let the total monthly income of the family be I.
From the survey data description:
Expenditure on Education = 18% of I
Expenditure on Travel = 8% of I
The problem states that the difference between these two expenditures is Rs. 4,000:
Difference=18%−8%=10% of I
10% of I=4000
100
10
×I=4000
I=4000×10=Rs. 40,000
Therefore, the total income of the family is Rs. 40,000.
