Answer 1

Answer:

If the simple interest for 6 years

be equal to 30% of the principal, it

will be equal to the principal efter

answer :- 20

Answer 2

Answer:

b> 20 years.

Let the principal = Rs X and rate of interest = R%p.a.

Then, S. I. = 30% of Rs X = 30/100 × X

Therefore, X × R × 6/100 = 30/100 × X

=> R = 30/6 = 5% p. a.

Let the time in which the principal is equal to simple Interest be there equal, then

X × 5 × t/100 = X => t = 100/5 years

$answer = 20 \: years...$
