Correct Answer: 20%
Solution:
Let the cost price of 1set sofa=CP1=500
and cost price of 2nd set=CP2=300
The profit percentage he made on second set twice the (Numerical value) loss made on the first set.
i.e SP2-CP2=2(CP1-SP1) where SP1 and SP2 are selling prices of first and second set
=> SP2+2SP1=1300 ----------------i
In entire transaction the trader make gain of 2.5%. What is loss percentage on the first set
SP1+SP2=\(\frac{112.5}{100}*(500+300) =900\)
=> SP1+SP2=900 --------------ii
by solving equation i and ii we get SP1=400 and SP2=500
so, the loss on first set= \(\frac{500-400}{500}*100 =20 %\)
