Question

In how many years does a certain sum amount to three times the principal at the rate of 50/3%?

Answer 1

Answer:

time = 12 years..

Step-by-step explanation:

let, principal = p.

amount = a = 3p

rate of interest = r.

interest = 3p - p = 2p

$interest = \frac{principal \times time \times rate \: of \: interest}{100} \\ or \: 2p = \frac{p \times time \times 50}{3 \times 100} \\ or \: 600 = time \times 50 \\ or \: time = \frac{600}{50 } = 12$
