If goods be purchased for Rs.990 and one third sold at a loss of 10%. At what gain percent should the remainder be sold so as to gain 40% on the whole transaction ?
Answer & explanation
Correct answer: option 2
In this type of questions we do not need actual given amount so,
Let total = 90
After one third sold at a loss of 10% remaining = 30 × \(\frac{9}{10}\) = 27
Total selling price should be 126 ( 140% of 90 )
Now two third has to be sold at = 126 - 27 = 99
Profit at which remaining has to be sold at = 99 - 60 = 39
= 39 × \(\frac{100}{60}\) = 65%
