Which one of the following represents the correct formula for crude birth rate (CBR), where B = live births during the year; P= Estimated mid year population of the area?

This question was previously asked in
RRB NTPC 2025 Under Graduate CBT 1 Question Paper PDF (20-Jun-2026) (Shift 3)
The correct answer is

(Births ÷ Population) × 1000

Crude Birth Rate (CBR) is defined as the number of live births during a year per 1000 of the mid-year population: \(\text{CBR} = \dfrac{B}{P}\times1000\).

The other combinations do not correctly represent the standard demographic formula for crude birth rate.

Hence, '(Births ÷ Population) × 1000' is the correct answer.
