If (0, 2) is the solution of 2x + 3y = k then find the value of k, by completing the activity:

Activity:

(0, 2) is the solution of the equation 2x + 3y = k.

Put `x = square and y = square` in the given equation;

∴ `2 xx square + 3 xx 2 = k`

∴ 0 + 6 = k

∴ `k = square`

If 2 and 5 are the roots of the quadratic equation, then complete the following activity to form quadratic equation:

Activity:

Let α = 2 and β = 5 are the roots of the quadratic equation.

Then quadratic equation is:

x2 − (α + β)x + αβ = 0

∴ `x^2 - (2 + square)x + square xx 5 = 0`

∴ `x^2 - square x + square = 0`

The following frequency distribution table shows the classification of the number of vehicles and the volume of petrol filled in them. To find the mode of the volume of petrol filled, complete the following activity:

Class
(Petrol filled in Liters)
Frequency
(Number of Vehicles)
0.5 - 3.5 33
3.5 - 6.5 40
6.5 - 9.5 27
9.5 - 12.5 18
12.5 - 15.5 12

Activity:

From the given table,

Modal class = `square`

∴ Mode = `square + [(f_1 - f_0)/(2f_1 -f_0 - square)] xx h`

∴ Mode = `3.5 + [(40 - 33)/(2(40) - 33 - 27)] xx square`

∴ Mode = `3.5 +[7/(80 - 60)] xx 3`

∴ Mode = `square`

∴ The mode of the volume of petrol filled is `square`.

The total value (with GST) of remote controlled toy car is ₹ 2360. Rate of GST is 18% on toys. Complete the following activity to find the taxable value for the toy car.

Activity:

Total value for toy car with GST = ₹ 2360

Rate of GST = 18%

Let taxable value for toy car be ₹ x

∴ GST = `18/100 xx x`

∴ Total value for toy car = (taxable value for toy car) + `square`  .....Formula

∴ 2360 = `square + square/100 xx x` 

∴ 2360 = `square/100 xx x`

∴ 2360 x 100 = 118x

∴ `x = (2360 xx 100)/square`

∴ Taxable value for toy car is ₹ `square`
