Ratio of monthly income to monthly expenditure of A is 11:9, respectively and monthly savings of A is Rs. 2880. Find the monthly income of A.
Let, monthly income and monthly expenditure of A is Rs. 11x and Rs. 9x respectively. So, monthly savings of A = 11x – 9x = Rs. 2x And, 2x = 2880 x = 1440 So, monthly income of A = 11 × 1440 = Rs. 15840
