D. Rs. 698
Simple Interest (SI) for 1 year = 854-815 = 39
Simple Interest (SI) for 3 years = 39 × 3 = 117
Principal = 815 – 117 = Rs.698

A. Rs.4000
B. Rs.9000
C. Rs.5000
D. Rs.6000
Let sum = P and original rate = R. Then
[(P * (R+2) * 3)/100] – [ (P * R * 3)/100] = 360
3P*(R+2) – 3PR = 36000
3PR + 6P – 3PR = 36000
6P = 36000
P = 6000

S.I. for 3 years = Rs. (12005 – 9800) = Rs. 2205.
S.I. for 5 years = Rs.[ (2205/3) x 5 ] = Rs.3675
Principle = Rs.(9800-3675) = Rs.6125
Rate=12%

A. 12.25%
B. 12%

D. 13.75%
Simple Interest, SI = (3875 – 2500) = Rs.1375
Principal, P = Rs. 2500
Time, T = 4 years
R = ?
R=100×SI/PT=100×13752/500×4
=100×1375/10000=13.75%

D. 334
Cash price = $3695
Deposit =1/3 of $3695
= $1231.67
Loan amount = $3695.00 − $1231.67
= $2463.33
Total cost of loan = $25.97 × 104
= $2700.88
Interest charged = total amount − loan
I = A − P
= 2700.88 − 2463.33
= 237.55
