|
The monthly incomes of Mohit and Prakash are in the ratio 2: 3 |
Suppose Income of Mohit = 2x Income of Prakash = 3x |
|
Their monthly expenditures are in the ratio 3: 5. |
Suppose Expenditure of Mohit = 3y Expenditure of Prakash = 5y |
|
Each saves Rs. 5000 per month. |
So, 2x – 3y = 5000 ……. (1) 3x – 5y = 5000 ……. (2) |
|
By solving both equation: |
We get, x = 2y Put x = 2y in above equations: x = 10000 y = 5000 |
|
Sum of monthly incomes of Mohit and Prakash = 5x |
Hence, 5x = 5 × 10000 = Rs. 50000 |
