Explanation

Step 1: Let the numbers be

$$8x\text{ and }3x$$

Step 2: Use the difference

8x−3x=20
$$5x=20\Rightarrow x=4$$

Step 3: Find the numbers

$$8x=32,$$

$$3x=12$$

Given:

Total students = 500
Present students = 300

Step 1: Find absent students

$$\text{Absent}=500-300=200$$

Step 2: Form ratio (Present : Absent)

$$300:200$$

Step 3: Simplify the ratio

Divide both by 100:

$$3:2$$

Explanation

Step 1: Understand the ratio

Boys : Girls = 3 : 2
Total parts = 3 + 2 = 5

Step 2: Find value of one part

$$frac{25}{5} = 5$$

Step 3: Find number of boys

$$3\times 5=15$$

Explanation

Two quantities are in inverse proportion when one increases and the other decreases.

Their product always remains constant.

Common in real-life situations like speed & time.

If one doubles, the other becomes half.

It is also called indirect proportion.

Direct Proportion → Both increase or decrease together.
