Solve question number one step by step
Answers
Step-by-step explanation:
1. (P)=Rs.810
(T)= 3 years
(R)= 5%
S.I= P×T×R/100
= 810×3×5/100
= 81×3×5/10
= 1215/10
=Rs. 121.5
A = S.I+P
= 121.5+810
= Rs.931.5
2.(P)=Rs.500
(T)=2 years
(R)= 5.5%
S.I= P×T×R/100
= 500×2×5.5/100
=500×2×55/1000
= 5×2×55/10
= 550/10
= Rs.55
A=S.I+P
= 55+500
= Rs.555
3. (T)=4 years
(R)=6%
(S.I)= Rs.90
S.I= P×T×R/100
90= P×4×6/100
P= 90×100/4×6
=Rs. 13,500
A= S.I+P
= 90+13,500
= Rs.13,590
4.(P)=Rs.800
(R)=7.5%
(S.I)= Rs.90
S.I= P×T×R/100
90= 800×T×7.5/100
T= 90×100/800×7.5
= 90/8×7.5
= 1.5 years
A= S.I+P
= 90+800
= Rs.890
5.(P)=Rs.3000
(T)=6 years
(A)=Rs .4530
A= S.I+P
4530 = S.I+3000
S.I= 4530-3000
S.I= Rs.1530
S .I= P×T×R/100
1530= 3000×6×R/100
R= 1530×100/3000×6
=153/3×6
= 153/18
= 8.5 %
