1] A man sells an article at 5% profit.If he had brought it at 5% less and sold it for Re.1 less,he would have gained 10%.The cost price of the article is what?
a]100 b]200 c]300 d]400
let the cost price of the article be Rs. x
profit = 5%
selling price = x+(5% of x) = 21x/20
cost price = x - (5% of x) = 95/100
If sold for Rs.1 less
SP = [(21x/20) - 1].Then gain % is 10
{(New SP - SP)/ SP} * 100 = 10
{(2x-20)/19x} *100 = 10
2x-20 = 19x /10
20x - 200 = 19x
x = 200

20x - 200 = 19x
x = 200

ReplyDeleteA man sells an article at 5% above its cost price.
ReplyDeleteIf he had bought it at 5% less than what he paid for it and sold it at Rs. 2 less, he would have gained 10%. Find the cost price of the article.
Let C.P = x.
then S.P = 105x/100.
If new C.P = 95x/100.
then S.P = (105x - 200)/100.
Profit = 10% of 95x/100 = 95x/1000.
Profit = S.P - C.P.
95x/1000 = (105x - 200)/100
95x/1000 = (105x - 200)/100 - 95x/100
95x/1000 = 105x - 200 - 95x)/100
95x/10 = 105x - 200 - 95x
95x = 10(10x - 200)
5x = 2000
x = 400
C.P = Rs.400
I have tried to solve this question by assuming c.p as 100. BT i can't solve it. Will u pls solve it by assuming c.p 100...
