Answer:

Given, rate r=5%, n=2 years, compound interest = Rs. 1100

Compound interest = Amount− Principal

Therefore, 1100=P(1+1005)2−P

⇒1100=P(1.05)2−P

⇒1100=1.1025P−P

⇒P=0.051100

⇒P= Rs. 22000

Simple interest = 100PRT

= 10022000×5×2

Simple interest = Rs. 2200

HERE IS ONE EXAMPLE :-

✅✅

HOPE THIS HELPS✅✅

Time = 2 years

Rate = 4%

Compound lnterest = Rs. 100

NOTE:

CI for 2 years =R+R+R×R/100

Where R - Rate of Interest

Combined Rate% of CI for 2 years =4+4+4×4100=8.16%

SI for two years

=2×4=8%

According to the question

SI for 2 years

=1028.16×8=Rs.100

Hence, required simple interest = Rs. 100
