Question
A man bought an article at a certain price, marked it
32% above the cost price and sold it after giving a discount of 25%. If he had bought it for 20% less and sold it for 600 more, his profit would have been 30%. Find the original cost price of the article.Solution
Let, the cost price of the article be Rs. '100x' So, marked price of the article = (100x × 0.32) = Rs. '132x' And, selling price of the article = (132x × 0.75) = Rs. '99x' According to question; (13/10) × (100x × 0.8) = (99x + 750) Or, 13 × 80x = 990x + 7500 Or, 1040x - 990x = 600 Or, 50x = 6000 So, x = 120 Cost price of the article = 100x = (100 × 120) = Rs. 12,000
√1764 + 35 × 8 + 39 = ?2
18% of 200 - 16% of 150 = ?
25% of 30% of 3/5 of 14500 =?
2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6)
7/3 of 4/5 of 15/56 of ? = 83
What will come in place of the question mark (?) in the following expression?
40% of 150 – ?% of 80 = 25% of 400
555.05 + 55.50 + 5.55 + 5 +0.55 = ?
64.5% of 800 + 36.4% of 1500 = (?)² + 38
What will come in the place of question mark (?) in the given expression?
25% of 1280 + (41 × 4) = ?2
Simplify the following expression:
((32)4 - 1)/33×31× (210+1)
