120g – 60g = 60g

11cm – 9 cm = 2 cm.

Thereforem every 60g increase from 60g, there will be incremental of 2cm.

240g – 60g = 180g 

15cm – 9 cm = 6 cm

180g increase will result in incremental of 6 cm (180/60 x 2).

360g – 60g = 300g

300 / 60 x 2 = 10 cm

10cm + 9 cm = 19cm

Extension of spring will be 19cm
