    Solution

    Let the income be x. The amount given to Emi = 22x/100 = 11x/50 Remaining amount = 39x/50 Expense on clothing = 5/12 x 39x/50 = 13x/40 13x/40 = 15,600 x = 1200 × 40 x = 48000 If, in February 2023, her salary increased by 20%: =48000 × 120/100 = 57600 Her salary (in Rs.) in February is 57600. Trick- February’s salary = 15600×12/5 × (100+20/100-22) =3120×12 ×120/78 =40×12×120 =57600.
