Principal amt with SI for 3 yrs = 815 = total sum of money.
Principal amt with SI for 4 yrs = 854 = total sum of money.
So, to find SI for 1 yr = 854-815 = 39,
So, SI for 3 yrs = 39 *3 = 117 or Si for 4 yrs = 39*4 =156,
Total sum for 3yrs = P+SI..815 = P + 117..P= 815 -117 = 698.
Principal amt with SI for 4 yrs = 854 = total sum of money.
So, to find SI for 1 yr = 854-815 = 39,
So, SI for 3 yrs = 39 *3 = 117 or Si for 4 yrs = 39*4 =156,
Total sum for 3yrs = P+SI..815 = P + 117..P= 815 -117 = 698.

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