Cost per thousand example 3

Media calculations and extra practice

Faculty-note examples and authored drills are labelled individually; practice marks are not PYQ marks

Optional practice question. A media placement costs ₹45,000 and delivers 300,000 impressions in the defined target. Calculate cost per thousand impressions. [2 practice marks]

Answer

Authored illustration: these numbers were chosen to explain a faculty-note concept. No matching supplied-data question was found in the 14 recovered APR papers. Standalone calculation drills are optional practice; their marks are author-set.

Given

CostImpressions
₹45,000300,000

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{45000}{300000}\times1000LaTeX: \text{CPM}=\frac{45000}{300000}\times1000

Step 2. Find cost per impression

45000\div300000=0.15LaTeX: 45000\div300000=0.15

Step 3. Scale to 1,000 impressions

0.15\times1000=150LaTeX: 0.15\times1000=150

Final answer: ₹150 per 1,000 target impressions.
