0.12

A

[1−(1+0.12)

−20

]

⇒ A=

[1−(1+0.12)

−20

30000×0.12

⇒ A=

[1−(1.12)

−20

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
