Q.
In the given figure find out the absolute and relative growth rate and choose the correct option
Absolute Growth Rate Relative Growth Rate
A) 1 $cm^{2}$ $1\ cm^{2}$
B) 100 $cm^{2}$ 5 $cm^{2}$
C) 5 $cm^{2}$ 100 $cm^{2}$
D) 0.5 $cm^{2}$ 100 $cm^{2}$
Explanation
Absolute Growth Rate (AGR) is the comparison of total growth per unit time Initial surface area $= 5\ cm^{2}$, Final surface area = $10\ cm^{2}$ AGR = Final surface area $–$ Initial surface area $= 10 - 5 = 5$ Relative Growth Rate (RGR) $= \frac{Final\ surface\ area - Initial\ surface\ area}{Initial\ surface\ area} \times 100$ $= \frac{10 - 5}{5} \times 100 \Rightarrow 100 = 100$
