A shopkeeper marked an article P% above its cost price and sold it for Rs. 1440 after giving a discount of 20%. If the ratio of cost price and selling price of the article is 25:30, respectively, then find the selling price if the article is sold at a profit of (P + 15)%.
Cost price of the article = (25/30) × 1440 = Rs. 1200 Marked price of the article = 1440/0.8 = Rs. 1800 P% = [(1800 – 1200)/1200] × 100 = 50% Or, P = 50 Desired selling price = 1200 × 1.65 = Rs. 1980
17.8 + 3/7 of 89.6 = ?
45% of 360 - 160 + ? = √324
2945 – 1508 + 3454 = ? + 2255
4.004 + 5.7(2.5 – 0.5) =?
134% of 1250 – 46% of 2120 = 4 × ?
64.5% of 800 + 36.4% of 1500 = (?)² + 38
[(√576 × √144) ÷ √1296]2 = ? ÷ 3
(5⁴) 5 × (25³)³=?
1672 ÷ 19 = ?% of 220
9999² + 1111² =?
