Question
A dealer purchased an item for Rs. βaβ and marked it
130% above its cost price, then sold it after applying two successive discounts of 700 and 10%, respectively, and made a profit of Rs. 3a/4. Find the marked price of the item.Solution
Let Cost Price (CP) = Rs. a Marked Price (MP) after 130% markup = CP + 130% of CP = a + 1.3a = 2.3a Selling Price (SP) after both discounts = 2.3a β 700 β 0.10 * (2.3a β 700) = 2.07a β 630 According to the problem, Profit earned = Rs. 3a/4. Therefore, SP = CP + Profit = a + 3a/4 = 7a/4 Or, 2.07a β 630 = 7a/4 Or, 1.28a = 630 Or, a = 1968.75 Therefore, Marked price = 230% * 1968.75 = Rs 4528.125

58% of 3300 - ?% of 2900 = 1740
390/? = √256 + 3.5
135.37 – 50.24 + 629.09 – 199.50 = ? – 214.68 + 42.65
32% of 4080 + 24% of 455 = x% of 4000

(√121 + √196) × 7 =? × 5
1300% of 2341 + 1200% of 6321 = ?
5/2 of 5/6 of 12/5 of 54 % of 5250 = ?
125% of 80 – 6 × 4 = ? × 13 – 54
