Question

a sum of money triples itself in 8 year find the rate of interest​

Answer 1

Answer:

25℅

Step-by-step explanation:

Let the sum ( principal ) be Rs 100

The sum triples in 8 years which is the Amount.

Number of years(N) = 8

Amount = 3× 100=300

S. I = A - P = 300-100=200 Rs

S. I = P × R × N /100

200 = 100 × R × 8/100

= 200 = 800×R/100

=200×100/800 = R

=20000/800 = R

=25 = R.

Rate = 25℅( It is correct answer)
