Step-by-step explanation:
Solution :
Here, Principal amount, P=10000 Rs
Rate, r=8.5% per annum
Time, t=1 year and 3 months So, Amount after first year =10000∗(1+8.5100)1
=10000∗108.5100=10850
So, interest after first year =10850−10000=850 Rs
Now, interest for 3 months in 2nd year =10850∗8.5∗3100∗12=230.56 Rs
So, total compound interest 850+230.56=1080.56 Rs
