Explanation

To find the price of 7 tube lights, first, calculate the cost of one tube light. Asad bought 12 tube lights for Rs. 6900.

Cost per tube light = Total cost / Number of tube lights

= 6900 / 12

= 575

Now, calculate the cost of 7 tube lights:

Cost of 7 tube lights = Cost per tube light * Number of tube lights

= 575 * 7

= 4025

Industries release waste directly into air or water from specific locations.

Explanation

Let's factorize 2x^2 - 7x + 3. We need to find two numbers that multiply to 2 × 3 = 6 and add to -7. These numbers are -6 and -1.

So, 2x^2 - 7x + 3 = 2x^2 - 6x - x + 3

= 2x(x - 3) - 1(x - 3)

= (2x - 1)(x - 3)

Explanation

Rauf's monthly income is Rs. 7200, and the pie graph shows his expenditure on education as 70°. To find the amount spent on education, we calculate the fraction of his income spent on education.

The fraction of income spent on education is 70° out of 360° (total degrees in a circle).

Fraction = 70° / 360° = 7/36

Amount spent on education = (7/36) × 7200 = 7 × 200 = 1400

Explanation

Let Haider's son's present age be x.

Haider's present age = 3x

After 10 years:

Son's age = x + 10

Haider's age = 3x + 10

The sum of their ages after 10 years will be 76:

x + 10 + 3x + 10 = 76

4x + 20 = 76

4x = 56

x = 14

Haider's present age = 3x = 3 × 14 = 42

Explanation

Vertical classification involves hierarchies, where each level increases in complexity, like from simple to advanced categories.

It is commonly used in taxonomy, education levels, and organizational charts to show structure from top to bottom.
