r
A
[1−(1+r)
−n

Thus 30000=
0.12
A
[1−(1+0.12)
−20
]
⇒ A=
[1−(1+0.12)
−20
]
30000×0.12
⇒ A=
[1−(1.12)
−20
]
3600

Answer:
Principal by Rajeev P =₹4000
rate r = 3%
n= 2
I= Pnr/100
= 4000 ×2×3/100
=₹2400
Principal by Rahul P =₹8000
rate r = 5%
n=3
I = Pnr/ 100
= 8000 ×5×3/100
= 120000/100
= ₹12000
I total = I +I = 2400 +12000=₹14400
