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
hope u got it.....plz mark as brainliest
