यदि two regions की population ratio 2:3 और area ratio 1:2 हो, तो उनकी density ratio क्या होगी?
If two regions have a population ratio of 2:3 and an area ratio of 1:2, what is their density ratio?

C. 4:3
Simple Explanation
Density ratio \(\frac{P_1/A_1}{P_2/A_2}\) से निकलेगा। Given ratios के अनुसार \(\frac{2/1}{3/2} = \frac{4}{3}\)। इसलिए density ratio 4:3 है और तीसरा विकल्प सही है। परीक्षा में ratio questions में population ratio को area ratio से divide करना useful है। / The density ratio is found from \(\frac{P_1/A_1}{P_2/A_2}\). Using the given ratios, \(\frac{2/1}{3/2} = \frac{4}{3}\). Therefore, the density ratio is 4:3 and the third option is correct. In examinations, for ratio questions, divide the population ratio by the area ratio.
