Wrong options (Question: 122998.0 )

option C is given 50 not 350 plz correct it

Question:
A dress is sold at a profit of 20%. If both the cost price and selling price are Rs.100 less the profit would be 5% more. Then the cost price is?
Options:
A) \(\unicode{x20B9} \)250
B) \(\unicode{x20B9} \)300
C) \(\unicode{x20B9} \)500
D) \(\unicode{x20B9} \)400
Solution:

Let CP = \(x\),

SP = \(x\) + 20% of\(x\) = 1.2\(x\).

New CP = \(x\) - 100,

New SP = 1.2\(x\)- 100.

New Profit,

1.2\(x\) -100 - \(x\) + 100 = 0.2\(x\)

New Profit = 25% of (\(x\) -100)

25% of (\(x\) - 100) = 0.2\(x\)

0.2\(x\) =\(25× \left ( \cfrac {(x-100)}{100} \right )\)

20\(x\) = 25\(x\) - 2500

5\(x\) = 2500.

\(x\)= 500.
So, the cost price was Rs. 500.
