Answer: Andy should invest RS. 2784.19 for 12 years .

Step-by-step explanation:

Since we have given that

Amount = Rs. 5000

Time = 12 years

Rate of interest = 5%

So, We need to find the sum:

Using "Compound interest" , we get :

$A=P(1+r)^t\\\\5000=P(1+0.05)^{12}\\\\5000=P(1.05)^{12}\\\\\dfrac{5000}{1.05^{12}}=P\\\\2784.19=P$

Hence, Andy should invest RS. 2784.19 for 12 years .

Let's set up a proportion.
3/20=x/100
Because 20*5=100, you can determine x by multiplying the numerator by 5 as well.
3*5=15
x=15
15%
