NN Store imported Notie mobile phones and Dricsin mobile phones in the ratio 8:5. After selling 120 Notie mobile phones and 135 Dricsin mobile phones, the ratio of Notie mobile phones and Dricsin mobile phones left was 8:3. How many Notie mobile phones did the store import?

(8x/13 - 120)/(5x/13 - 135) = 8/3

(8x - 1560)/(5x - 1755) = 8/3

=> 24x - 4680 = 40x - 14040

=> 16x = 9360 => (x = 585)

= 8x/13 = 360
