Explanation
Let the buyer has 100 items and each costs 1 Rs
The cost price of 100 items=100Rs
Profit percentage =10
So the selling price of one item=1+10/100
=1.1
No of items left after theft =100−20
=80
the selling price of 80 items =80×1.1
=88Rs
Loss % = (100)-(80)/100 (100) =12%

Explanation
Let the percentage deduction in weight be y%
y−4100−y×100=20⇒y−4100−y=15⇒5y−20=100−y⇒6y=120⇒y=20
Hence, for a meter, length used = (100 - 20)% of 1 m
= 80% of 100 cm = 80 cm
