    Let the monthly incomes of Aryan and Babban be 3x and 4x, respectively. Suppose their monthly expenditures are 5y and 7y, respectively. Since each saves Rs 15,000 per month, Monthly saving of Aryan: 3x−5y=15,000Monthly saving of Babban: 4x−7y=15,000 solve it ?? you will get the answer ⏩Monthly income of Aryan = 3×Rs 30,000=Rs 90,000 Monthly income of Babban = 4×Rs 30,000= Rs 1,20,000
