Question

in how many years a sum of money will become three times at 5% simple interest per annum​

Answer 1

Answer:

Assume principal to be 100RS

Amount after 5years = 300RS (since it triples)

So intrest = 200RS (principal - amount = interest)

Inorder to become 5times i.e 500RS, interest has to be 400RS on the principal amount which is 100Rs

200RS →5years

400Rs → ?

= 400*5/200 =10years
