Answer 2

Answer:

I" = 600

Step-by-step explanation:

given,

sum of money will be rupees  I (200) after 5 year

for next 5 year principal is doubled.

Total interest = ?

we know

$I = \dfrac{PRT}{100}$

now,

new for next five year

$I' = \dfrac{2 PRT}{100}$

$I' = 2 I$

Total interest

I" = I + I'

I" = I + 2 I

I" = 3 I

I" = 3 x 200

I" = 600
