Let the salary of Elina be Rs. 100x Tax paid by her = 100x X 0.8 = 8x After paying tax income of Elina = 100x - 8x = Rs. 92x Total expenditure of Elina on rent, education and food: = (92x X 0.5 + 4500) = Rs, (46x + 4500) ATQ, 92x - (46x + 4500) = 18500 Or, 46x - 4500 = 18500 + 4500 Or, 46x = 23000 So, 'x' = 500 Therefore, required amount = 100 X 50 X 0.8 = Rs. 4000
