We shall also study the population growth and depreciation of the value of movable and immovable assets.

Answer 2

Answer: 33.1%

Explanation:

SI= P*R*T/100

A/Q

SI= P*30*4/100*12(devide by 12 becauss time is in months)

So,

SI=P/10

Now,

CI=P(1+r/100) -P

Therefore,

CI= P[(1+r/100) ^1/3-1]

on solving,

SI=CI

which means

P/10= P[(1+r/100) ^1/3-1]

On solving,

r/100= 331/1000

So,

r= 33.1%
