What would a student report nearly after 30 minutes of placing duly cleaned strips of aluminium, copper, iron and zinc in freshly prepared iron sulphate solution taken in four beakers ?

There will be no reaction in the beakers having Fe strip and Cu strip.

The solution having Al and Zn strip will show reaction. The solution of FeSO4 having Al and Zn strip will become colourless.
