      Solution

      ATQ,

      Let the income of Meena be Rs. 100n

      Amount spent on groceries = 0.18 × 100n = Rs. 18n

      Amount spent on rent = 0.12 × 100n = Rs. 12n

      Remaining income = 100n - 18n - 12n = Rs. 70n

      Amount spent on travel = 0.30 × 70n = Rs. 21n

      Now remaining income = 70n - 21n = Rs. 49n

      Amount spent on shopping = 0.25 × 49n = Rs. 12.25n

      Savings = 49n - 12.25n = Rs. 36.75n

      Now, 12n = 3,600

      So, n = 300

      Therefore, savings = 36.75 × 300 = Rs. 11,025
