Answer : 2. "Rs. 420"
Explanation :
Answer: B) Rs. 420 Explanation: As given in the question, 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 +13.333300 x P => S.P = 7P6 According to the question, 7P6 - 300 = 2P - 300 => 5P = 1800 => P = Rs. 360 Hence, the increased S.P = 360 x 7/6 = Rs. 420.
