Given

CostImpressions
₹18,00060,000

To find

Cost for 1,000 target impressions.

Formula and why

\text{CPM}=\frac{C}{I}\times1000LaTeX: \text{CPM}=\frac{C}{I}\times1000

C is the placement cost in rupees; I is target impressions. Dividing gives rupees per impression, then multiplying by 1,000 gives rupees per thousand.

Step-by-step solution

Step 1. Substitute values

\text{CPM}=\frac{18000}{60000}\times1000LaTeX: \text{CPM}=\frac{18000}{60000}\times1000

Step 2. Find cost per impression

18000\div60000=0.3LaTeX: 18000\div60000=0.3

Step 3. Scale to 1,000 impressions

0.3\times1000=300LaTeX: 0.3\times1000=300

Final answer: ₹300 per 1,000 target impressions.
