Answer with explanation:
Initial Population of Rice weevil in an Insect Study = 400
Rate at which population of Rice weevil is growing =150 %
⇒Growth formula is Given by
[tex]=I_{0}\times [1+\frac{R}{100}]^n\\\\ \text{where }I_{0}=\text{Initial Population}[/tex]
R=Rate Constant
n=Duration or time Period
⇒Population After a week is given by,if we take a week as,n=1.
[tex]=400\times [1+\frac{150}{100}]^1\\\\=400 \times 1.5\\\\=600[/tex]
