The marked price of an article is increased by 25% and the selling price is increased by 16.66%,then the amount of profit doubles. If the original marked price be Rs.400 which is greater than the corresponding cost price by 33.33%, what is the increased selling price?
a. 240
b. 360
c. 420
d. 600
I would say give away is "original marked price be Rs.400 which is greater than the corresponding cost price by 33.33% "
Which Gives C.p. as 300.
Now lets say Original S.P. is x
New S.P. will be (7/6)x
Therefore,
(7/6)x - 300 = 2[ x- 300]
Solving for x,
x=360
New S.P =7/6x=420
Given, Marked price is 25% more than the Cost price.
=> C.P of the article = 34 x 400 = 300
Now,
Let the original S.P of the article be Rs. P
Now the new S.P = P + (16.666 +13.333)x P/100
=> S.P = 7P/6
According to the question,
7P/6 − 300 = 2(P − 300)
=> 5P = 1800
=> P = Rs. 360
Hence, the increased S.P = 360 x 7/6 = Rs. 420.
