Answer 2

Answer:

Solution

Given that -

p - 6000

R - 5%

Amount 6000+6000 = 12000

We know that

$si = \frac{p \times r \times t}{100}$

Ans also that - SI = Amount - Principal

Let's solve

$A - P = \frac{p \times r \times t}{100}$

putting value

$12000 - 6000 = \frac{6000 \times 5 \times t}{100}$

$6000 = 300t$

$\frac{6000}{300} = t$

$20 \: = t$

Ans. It will take time 20 year .
