Question

In how much time will a sum of money become triple itself at 10% per annum simple interest

Answer 1

Solution:

Let the principal ( P ) = x

Amount ( A ) = 3x

Simple interest ( s.i ) = A - P

= 3x - x

= 2x

Rate of interest ( R ) = 10%

Let the time = T years

Now ,

( PTR )/100 = s.i

=> T = ( 100 × s.i )/( PR )

= ( 100 × 2x )/( x × 10 )

= 10 × 2

= 20 years
