Question

2. A sum amounts to 5940.50 in 2 years at 9% per annum compound interest. find sum​

Answer 1

Step-by-step explanation:

Let,the sum be=P

For first year, Principal=P. Time=1. Rate= 9%

S.I= PTR/100 =P×1×9/100=9P/100

Amount=Principal+Interest

=P+9P/100

=109P/100

For Second year, Principal=109/100. Time=1. Rate= 9%

SI=PTR/100=109P/100×1×9/100=981P/10000

Amount= 109P/100+981P/100=11881P/10000

Now, according to the question.

11881P/10000=5940.50

or,P=5940.50×10000/11881

or,P=5000(594050, divisible by 11881, that's (5×11881(

Ans,The Sum is 5000
