Answer 2

Answer:

The simple interest on 1800 at 5whole 1 upon2 per annum for 2 years is :​

Step-by-step explanation:

Let the sum=P Rs.

S.I=50 Rs.

Rate of interest=5 %

Time =2 years.

S.I=P×R×T/100

50=P×5×5/100

P= 50×100/5×2

C.I. of 500 Rs

Amount=500(1+5/100)2 ⇒500× 105/108×105/100⇒500×21/20 ×21/20⇒551.25C.I=551−500−51.25Rs.
