Q6. A man sells one third of a sugar at Rs. 3/kg and loses 20% and sells another kind of sugar at Rs. 5/kg and gains 25%. He mixed the two in equal proportion and sells the mixture at rs. 6/kg find his gain % ?
a. 52.33%
b. 54.83%
c. 56.67%
d. None of these
ans: b. 54.83%
Rs 3/kg - loss 20% => price = 3/0.8 = 3.75
Rs 5/kg - profit 25% => price = 5/1.25 = 4
cost price when mixed in equal prop = 7. 75/2 = 3.875
profit % = 2.125/3.875 x 100 = 54.83%

LET COST PRICE OF50 METER CLOTH=100 rs
so cost price of 10 m cloth=20 rs.
so selling priceof 50 m cloth=(100)+(20)=120 rs.
profit %=((120-100)/100)*100=20%
