Let the image distance be denoted as “v” cm.
 
Using the general equation of refraction through a curved surface,
[µ₂/v] – [µ1/u] = [(µ2 - µ1)/R]
Substituting the given values, we get
[1/v] – [-(3/2)/20] = [(1 – 3/2)/20]
⇒ 1/v = - [3/40] – [1/40]
⇒ 1/v = [-3-1]/40
⇒ 1/v = -4/40
⇒ 1/v = - 1/10
⇒ v = - 10 cm
Thus, the flower appears to be 10 cm above its actual position.
