1 Answer

Answer :

Let CP= x

SP= 140x/100 = 14x/10

CP= 80% 0f x= 8x/10

then, SP =14x/10+70

14x/10 + 70= 350%of 8x/10

14x/10+70=350/100*8x/10=28x/10

70=28x/10-14x/10

70=14x/10

X=700/14

X=50

Description : Sridevi sells an article at a profit of 50%. If she had bought it at 40% less and sold it for Rs.21.50 less, She would have gained 60%. Find the cost price of the article.

Last Answer : 1st selling price=150% of x = 150x/100 = 15x/10 New Cost price=60% of x = 60x/100 = 6x/10  2nd selling price = 160% of 6x/10 = 160/100 * 6x/10 = 96x/100  Therefore 15x/10 – 96x/100 = Rs.21.50  X=Rs.39.81  Therefore cost price of the article = Rs.40 (approx.)

Description : A salesperson has goods of worth Rs.12000. He sold half of the goods at a gain of 24%. At what profit per cent should he sell the remaining half of the stock so that he gets36% profit on the whole?

Last Answer : CP of goods = 12000 For 36% gain, total SP =12000 + (36/100*12000) = 16320 SP of goods worth 6000 at 24% profit = 6000 + (24/100*6000) = 7440 Therefore, SP of remaining goods = (16320-7440) = 8880 Let ... % for remaining goods be x. Then, =>6000*(100+x)/100=8880 =>100+x=8880/60 x=148-100=48
