Here;
P+4I = 854,
p+3I = 815,
I = 39,
p = 698.
P+4I = 854,
p+3I = 815,
I = 39,
p = 698.

P + 3(I) = 815,
P + 4(I) = 854,
Totally = I = 39,
P + 3 × 39 = 117,
854 - 117 = 698.
P + 4(I) = 854,
Totally = I = 39,
P + 3 × 39 = 117,
854 - 117 = 698.

@All.
Sum of Amount = Principal Amount + Interest.
here given Sum of Amount is,
815 ----> 3 year.
854 ----> 4 year.
854 - 815 = 39 Simple Interest Per year (because we have a question for per year interest)
39 * 3 = 117.
Sum of Amount = Principal Amount + Interest.
815 = P + 117,
P = 815-117,
P = 698.
Sum of Amount = Principal Amount + Interest.
here given Sum of Amount is,
815 ----> 3 year.
854 ----> 4 year.
854 - 815 = 39 Simple Interest Per year (because we have a question for per year interest)
39 * 3 = 117.
Sum of Amount = Principal Amount + Interest.
815 = P + 117,
P = 815-117,
P = 698.

854 - 815 = 39,
39 * 4 = 156,
854 - 156 = 698.
39 * 4 = 156,
854 - 156 = 698.
