ANSWER
Given that simple interest for 2 years is Rs.800
i.e., Simple interest for 1st year is Rs.400
and simple interest for 2nd year is also Rs.400
Compound interest for 1st year will be 400
and Compound interest for 2nd year will be 832−400=432
you can see that compound interest for 2nd year is
more than simple interest for 2nd year by 432−400=Rs.32
Rs. 32 is the interest obtained for Rs.400 for 1 year
R=

Answer:
Step-by-step explanation:
Given that simple interest for 2 years is Rs.800
i.e., Simple interest for 1st year is Rs.400
and simple interest for 2nd year is also Rs.400
Compound interest for 1st year will be 400
and Compound interest for 2nd year will be 832−400=432
you can see that compound interest for 2nd year is
more than simple interest for 2nd year by 432−400=Rs.32
Rs. 32 is the interest obtained for Rs.400 for 1 year
R= PT
100×SI =
400×1
100×32 =8%
Difference between compound and simple interest for the 3rd year
= Simple Interest obtained for Rs.832 = 100
PRT = 100
832×8×1
=66.56
Total difference between the compound and simple interest for 3 years
=32+66.56=Rs.98.56
