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. Rs. 600
B. Rs. 420
C. Rs. 360
D. Rs. 300
Solution (By Examveda Team)
Given Original Marked Price = Rs. 400
Let CP was = X.
Now,
X + 33.33% of X = 400
100X + 33.33X = 400 *100
X = 40000 /133.33 = Rs. 300 (Aprox.)
Let initial Profit was y, So
SP = 300 + y
New Profit = 2y and
New SP = (300 +y) + 16.66% of (300 +y) = (300 +y)*7/6
Now,
350 + 7y/6 -300 = 2y
5y/6 = 50
y = 60
Original Profit = Rs. 60
New Profit = 2y = Rs. 120
So, New SP = 300 + 120 = Rs. 420

12(sp-300)= 7sp-1800
12sp-3600= 7sp-1800
Sp= 360
Sp1= 7/6)*360= 420
Original M.P.= 400
Hence, C.P.=3/4*400=300
S.P increased by 16.66% whose fractional value is 1/6. So, if previous S.P was 6 then it is 7 now. So, C.P. should be 5 because previous profit is (6-5)=1 and current profit is (7-5)=2 which is double of the previous profit.
Now the value of 5 units is given which is 300.
Hence the value of 7 units(which is the increased S.P.) is 420 (Ans)
We have to consider all the scenario. Please, read question twice, you will understand it properly.
