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.

It is given in sum that SI of 3yrs is 815 so why we need to multiply 3 with 39 to get SI for 3 years?

S.I for one yr=854-815=39
for 4 years=4*39=156
hence,854-156=698
i think it will be simple....
for 4 years=4*39=156
hence,854-156=698
i think it will be simple....

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

Here you can do it by another S. I 1 yr = 39, in 4 years =156, & principle=854 - 156 = 698.

A2T1-A1T2/T1-T2.
The above formula is applies here,
854 * 3-815 * 4/3-4,
2562-3260/-1,
= 698.

3y--815,
4y--854,
----------
1y--39,
So, 3y ---39 x 3 = 117
Principal is = (815-117) = 698
4y--854,
----------
1y--39,
So, 3y ---39 x 3 = 117
Principal is = (815-117) = 698

PTR/100 = 815
P*3*R/100 = 815
R/100=854- 815
p * 3 * 39 = 815
P * 117 = 815
p = 815-117 = 698
P*3*R/100 = 815
R/100=854- 815
p * 3 * 39 = 815
P * 117 = 815
p = 815-117 = 698

Why we find out only for three years. Is principle is found on only for the first year money?

3 year - 815,
4 year - 854,
4 yr - 3 yr= 854-815,
1 yr=39,
39*3=117,
Sum= 815-117= 698.
4 year - 854,
4 yr - 3 yr= 854-815,
1 yr=39,
39*3=117,
Sum= 815-117= 698.
