Answer 1

Answer:

option c.............. .. .......

Answer 2

Answer:

Let the sum=P Rs.

S.I=56 Rs.

Rate of interest=5 %

Time =2 years.

S.I=  P×R×T/100

​56=   P×5×5/100

​P= 56×100/5*5

​   =224Rs.

C.I. of 224 Rs

Amount=224(1+  5/100 )  2

⇒224×105/100*105/100

⇒224× 21/20*21/20

⇒246.96

C.I=246.96−224=22.96Rs.
