Question
A shopkeeper priced an article at 75% above its cost
price and offered a 30% discount on it during the sale. Alternatively, if he had applied two consecutive discounts of 20% and 10% instead, he would have earned Rs. 168 more in profit. Determine the cost price of the article.Solution
Let the cost price of the article = Rs. x So the marked price of the article = Rs. 1.75x Original selling price of the article = 1.75x × 0.70 = 1.225x Increased selling price of the article = 1.75x × 0.80 × 0.90 = Rs. 1.26x According to question: 1.26x – 1.225x = 168 0.035x = 168 x = 4800 So the cost price of the article = Rs. 4,800Â
[490 of 7 - (13)2 of 5] - 1228 = ?
 √256 * 4 – 30% of 190 + ? = 110% of 220
3% of 3000 x ?% of 2000 = 3600
125% of 129 ÷ 43 × 28 ÷ 7 = ? ÷ √16
(15 × 16) + 242= ? × 16
? = 80% of 30% of (50 × 150) + 400
- What will come in the place of question mark (?) in the given expression?
(15 - 19 + 10) ² + ? = 45 X 2 If √3n 729, then the value of n is equal to:
- Simplify the following expression:
(48% of 800 × 3) ÷ 6 + 440 ÷ √25 - 14² 3 √(432 – 13 + 9 × 32) = ?
