Question

I want someone to chat with......

But before that pls answer this question.... with steps....

Answer 1

As this is simple intrest the intrest in each year wiil same.

ex if sum is 900 an simple intrest is rs 20

then  

first year SI amount is 900+20=920

2nd year SI =920+20=940....

3rd year Si=940+20=960

by looking the above we can easily get the simple intrest i.e 960-940=20...

so acc to question 3 yr SI=815

4 yr SI=854

so intrest=854-815=39

for 1 yr it  is39

for 3 yr 39X3=117

so sum(Principle)=815-117=698

chta me

Answer 2

so,the interest in 4 years will be

39×4=156

so,the sum will be :(854-156)=698
