Answer With SolutionAnswer: 96cm
Solution: let’s say jane’s tree grow by 1cm in X time, and in the same time ali’s tree grow by 2cm and pat’s tree grow by 3cm.
so to grow 108 – 90 = 18 cm, pat’s tree should take 18/3 = 6X time and jane’s tree should grow by 6cm in the same time.

My answer is 96.
Initial all tree height is 90cm. The ratio of grow tree of jane:ali:pat was 1:2:3. When pat tree was 108 then jane’s tree was (108-90 = 18/3=6) 6cm grow means total grow of jane’s tree was = 90+6 = 96
