Simple interest for 1 year = 854 - 815 = 39.
Simple interest for 3 year = 39 * 3 = 117.
Simple interest for 4 year = 39 * 4 = 156.
Now,
Subtract the given amount of each simple interest amount
A = 815-117 = 698
B = 854-156 = 698
Both are same, so;
So, the answer is 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.

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

We can subtract it from 854 also but since we had calculated for 3 years we subtract it from 815 if you want to subtract from 854 do this.
4 x 39 = 156,
854 - 156 = 698.
4 x 39 = 156,
854 - 156 = 698.
