please change name
and amount
Principal for the first year = Rs 3,000

Interest for the first year=Rs3,000 x 5 x 1100 = Rs 150

Amount at the end of the first year = Rs 3,000 + Rs 150 = Rs 3,150

Principle Interest for the second year=Rs 3,150 x 5 x 1100 = Rs 157.50

Amount at the end of the second year = Rs 3307.50

Compound interest=Rs 3,307.50 – 3,000 = Rs 307.50

Answer:

Step-by-step explanation:

Calculate 20000*12%+12500*24%

=5400 this is the interest amount we get

So difference between the 15% if 50000 and 5400 =2100.

So calculate the remaining amount on remaining interest

For annual amount we can take t=1 year.

So interest =(PTR)/100

2100=((50000-(20000+12500))*1*r)/100

r=12%
