## Numerical practice

A campaign records 20,000 impressions, 400 clicks and ₹8,000 spend. Calculate CTR, average CPC and CPM. If 16 clicks lead to conversions, calculate conversion rate using clicks as the denominator and explain why the denominator must be stated.

## Answer key

- CTR = 400 ÷ 20,000 × 100 = 2%.
- Average CPC = ₹8,000 ÷ 400 = ₹20.
- CPM = ₹8,000 ÷ 20,000 × 1,000 = ₹400.
- Conversion rate = 16 ÷ 400 × 100 = 4%, when clicks are the denominator.

## Study method

For each unit, prepare a one-page summary, practise definitions, write one applied example, and attempt the questions without notes. Review errors by concept rather than memorizing only the answer. Consult the [official JNTUH R25 MBA syllabus](https://jntuh.ac.in/uploads/academics/R25MBASyllabus.pdf) for the prescribed unit scope.
