Answer 1

dude based on the question I got only this far.....i guess this is it...

Answer 2

Answer: $\frac{27p}{25}$

Step-by-step explanation:

let sum is p and rate of interest is r.

so interest is p/25 and time is r because time = rate of interest.

as we know for simple interest

$i=\frac{p*r*t}{100}$

so

$\frac{p}{25}=\frac{p*r*r}{100}\\\\r^{2}=4\\\\r=2$

so rate is 2% per annum and time is 2 years

again for amount after 4 years

as we know simple interest is same for each year

as interest for 2 years is p/25.

so interest after 4 years is $\frac{2p}{25}$

so amount will be p+$\frac{2p}{25}$

=$\frac{27p}{25}$
