Amount saved by Sarla = 0.3125 × 8000 = Rs. 2500
Amount spent on food = x/100 × 8000 = Rs. 80x
Amount spent on rent = (x + 20)/100 × (8000 – 80x) = (x + 20)(80 – 0.8x)
Or, 80x + (x + 20)(80 – 0.8x) = 8000 – 2500 – 1920 = 3580
Or, 80x + 80x + 1600 – 0.8x 2 – 16x = 3580
Or, 0.8x 2 – 144x + 1980 = 0
Or, x 2 – 180x + 2475 = 0
Or, x 2 – 165x – 15x + 2475 = 0
Or, x(x – 165) – 15(x – 165) = 0
Or, (x – 15)(x – 165) = 0
Or, x = 15 [x = 165 is not possible]
