-
- S.I = PTR/100
S.I =15000*9*2/100
S.I= 2700
C.I =P(1+r/100)^n -P
C.I= 12000(1+8/100)^2-12000
C.I=1996.8
total amount in 2 years
as interest = S.I +C.I
= 2700+1996.8
=4696.8 - 9 years agoHelpfull: Yes(29) No(1)
- 4696.8 by using S.I and C.I formulas
- 9 years agoHelpfull: Yes(1) No(0)
- 4696.8 by S.I = PTR/100
S.I =15000*9*2/100
S.I= 2700
A=P(1+r/100)^n
C.I= A-P=12000(1+8/100)^2-12000
C.I=1996.8
total amount in 2 years
as interest = S.I +C.I
= 2700+1996.8
=4696.8
