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.

For 3 years Rs. 815.
For 4 years Rs. 854.
Then 854 - 815 = 39 (Interest for 1 year).
Interest of 3 year 39 * 3 = 117.
Total amount of 3 years - Interest of 3 years = principal amount.
815 - 117 = 698.
For 4 years Rs. 854.
Then 854 - 815 = 39 (Interest for 1 year).
Interest of 3 year 39 * 3 = 117.
Total amount of 3 years - Interest of 3 years = principal amount.
815 - 117 = 698.
