20% were stolen, or 120 of them
480 left, and at 10 per 25 pounds, that is 1 per 2.5 pounds or 480 for 1200 pounds, using property of proportions.
He paid 1000 pounds for everything, so the profit was 200 pounds.

~~~~~~~~~~~~~~~~~~~~~~~~~~ 

20% of 600 is 0.2*600 = 120.


Hence, 120 biscuits were stolen and 600 - 120 = 480 were sold at  10 for  £25.


So, the trader collected %28480%2F10%29%2A25 =  £1200.


He gained  £1200 - £1000 =  £200.
