Comparing Quantities Class 8 Important formulas.

  1. Ratio: A ratio is a comparison of two quantities of the same kind by division. If the ratio of two quantities a and b is a:b, it can also be written as a/b.

  2. Proportion: A proportion is an equality of two ratios. If a:b = c:d, we say that a, b, c, and d are in proportion. This can also be written as a/b = c/d.

  3. Percentage: Percentage is a fraction of 100. It is denoted by the symbol '%'. If x is the percentage of y, then it can be represented as (x/100) * y.

  4. Profit and Loss: Profit is the amount earned when the selling price is higher than the cost price, while loss is the amount incurred when the selling price is lower than the cost price. Profit and loss can be calculated using the following formulas:

    Profit = Selling Price - Cost Price Loss = Cost Price - Selling Price Profit or Loss Percentage = (Profit or Loss / Cost Price) * 100

  5. Discount: Discount is the reduction in the marked price of an article. If a discount of d% is given on the marked price, then the selling price can be calculated using the following formula:

    Selling Price = Marked Price - (d/100) * Marked Price

  6. Simple Interest: Simple interest is the interest calculated only on the principal amount of a loan or investment. If P is the principal amount, R is the rate of interest, and T is the time period, then simple interest can be calculated using the following formula:

    Simple Interest = (P * R * T) / 100

class 8 comparing quantities extra questions and answers

  1. The ratio of the ages of A and B is 3:4. If the age of B is 28 years, find the age of A.

Solution: Let the age of A be 3x years. Then, the age of B is 4x years. From the given information, we know that 4x = 28, so x = 7. Therefore, the age of A is 3x = 21 years.

  1. The price of a dozen mangoes is $36. Find the cost of 8 mangoes.

Solution: Since a dozen has 12 mangoes, the price of one mango is $36/12 = $3. Therefore, the cost of 8 mangoes is 8 x $3 = $24.

  1. The length of a rectangle is 20% more than its breadth. If the breadth is 10 cm, find the length of the rectangle.

Solution: Let the length of the rectangle be L cm. From the given information, we know that L = 1.2 x breadth. Substituting the value of breadth as 10 cm, we get L = 1.2 x 10 = 12 cm. Therefore, the length of the rectangle is 12 cm.

  1. A mixture contains milk and water in the ratio 4:3. If the total quantity of the mixture is 35 litres, find the quantity of water in it.

Solution: Let the quantity of milk in the mixture be 4x litres and the quantity of water be 3x litres. From the given information, we know that 4x + 3x = 35. Therefore, x = 5. Hence, the quantity of water in the mixture is 3x = 15 litres.

  1. The height of a triangle is 60% of its base. If the base is 20 cm, find the height of the triangle.

Solution: Let the height of the triangle be h cm. From the given information, we know that h = 0.6 x base. Substituting the value of base as 20 cm, we get h = 0.6 x 20 = 12 cm. Therefore, the height of the triangle is 12 cm.
