Explanation:

Let the number of parents be x who has been asked for the donations.
People already solicited = 60% of x = 0.6x
Remaining people = 40% of x = 0.4x
Amount collected from the parents solicited= 1200 *0.6x = 720x
720x = 75%;
Remaining amount = 25% = 240x
Thus, Average donations from remaining parents = 240x /0.4x = 600
