Question
A Shopkeeper gives 2 articles free on the purchase of
every 10 articles. He also allows a discount of 20% to customer and still earn 25% profit. Find the ratio of the cost price to the marked price of the article?Solution
Offer of the Shopkeeper: Buy 10 get 2 free = 12 articles Let the marked price of 1 article be Rs. 10 Marked Price of 12 articles = 10× 12 = 120 Selling Price of 10 articles = 10 × 10 = 100 Actual Selling Price of 10 articles (less discount) = 100 – 20 = 80 Profit % = 25 % ∴ Cost Price = 80 × 100/125 =64 Cost Price: Marked Price = 64: 120 = 8:15
? = 685.24 + 1024.97 – 9.992 Â
8.15 of 124.95 ÷ 40.13 + 249.84 X 14.18 - √325 X 149.87 = ? X 10.85
8 × 1099.95 ÷ 20.03 + 187.95 = ? × 3.96
What approximate value will replace the question mark (?) in the following?
? =...
20.02 × 36.25 + 128.02 = ? + 364.04
2 (1/4)% of 7999.78 + {49.77% of 899.71} + √144.14 - 20% of 1499.83 = ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
(1440.13 ÷ 31.77) × (√168.69 + 16) - (24.87% of 719.99) = ?
(4.88 × 5.76)2 - ?2 = 39.89 × 19.86
15.232 + 19.98% of 649.99 = ? × 4.99
