Rs. 650
Rs. 690
Rs. 698
Rs. 700
Answer: Option
Explanation:

S.I. for 1 year = Rs. (854 - 815) = Rs. 39.

S.I. for 3 years = Rs.(39 x 3) = Rs. 117.

Principal = Rs. (815 - 117) = Rs. 698.

SI for 1 Year = 854 - 815=39,
SI for 3 year = 39 * 3 = 117,
And the Amount was = 854 - 117 = 698.

S.I for 1 year = 854 - 815 = 39.
S.I for 3 year = 39 * 3 = 117.
S.I 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.
