Question
A shopkeeper purchased an article for Rs. βaβ and
marked it 140% above its cost price and sold it after giving two successive discounts ofΒ Rs270 and 20%, respectively and earned a profit of Rs. 4a/5. Find the marked price of the article.Solution
Selling price of the article = a + (4a/5) = Rs. (9a/5) So, (9a/5) = (2.4 Γ a β 270) Γ 0.80 Or, 1.8a = (2.4a β 270) Γ 0.80 Or, 2.25a = 2.4a β 270 Or, 0.15a = 270 Or, a = 1800 So, marked price of the article = 2.4 Γ 1800 = Rs. 4320
3% of 842 ÷ 2% of 421 = ?
26 2 β 13% of 400 + (529 Γ· 23 2 ) = ? 2Β
Determine the simplified value of the given mathematical expression.
[(4 √ (7) + √ (7)) × (7 √ (7) + 6 √ (7))] - 87 = ?
...(190/38) Γ (55/5) + (306/18) = ?
72 x 60 x 22 x 32 =?
1240 Γ· ? = 242 + 123 β 514 Γ 4
82% of 400 + √(?) = 130% of 600 - 85% of 400
The value of ((0.27)2-(0.13)2) / (0.27 + 0.13) is:
