Question
A shopkeeper bought two articles for Rs. 150 each. If he
sold one of them at 40% profit and the other at 30% loss, then find the difference between the selling prices of both the articles.Solution
Selling price of one of the articles = 150 × 1.4 = Rs. 210 Selling price of the other article = 210 × 0.7 = Rs. 105 Required difference = 210 – 105 = Rs. 105
9.89 x 4.99 + 2.01 x 49.89 = ?% of 299.69
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.)...
A regular hexagon has a side length of 8 units. What is the area of the half of the hexagon?
 5983.987 + 59832.999 – 598.873 = ?
125.9% ÷ 9.05 x 99.98 = ? - 69.97 × √324.02 ÷ 5.98
420.11 ÷ 13.98 × 5.14 – 124.9 = √?Â
What approximate value will come in place of question (?) in the following given expression? You are not expected to calculate the exact value.
...12, 16, ?, 36, 52, 72Â
What approximate value should replace the question mark?
150.91 − √361 × 4 + 1200.30 ÷ 6.02 = ?
5466.97 - 3245.01 + 1122.99 = ? + 2309.99
