Answer 2

$Answer \:$

We know that :

Amount = Principal + Interest

Interest = Amount + Principal

= 5600-5000

=rs 600

$r = \frac{i \times 100}{p.t}$

$r = \frac{600 \times 100}{5000 \times 4} \\ = > r = \frac{6000}{20000} \\ = > r = 3\%$

Now,

we have to the interest.

Amount = RS 6900

Principal = RS 6000

Interest = amount - principal

= RS (6900-6000)

= RS 900

$time \: = \frac{i \times 100}{p \times r}$

$time = \frac{900 \times 100}{6000 \times 3} \\ = > time = \frac{90000}{18000} \\ = > time = 5 \: year \:$

Therefore, The time is 5 year.
