Question

In how many years a sum will be 3
times at the simple rate of interest 5% per ​

Answer 1

Answer:

60 YEARS

Step-by-step explanation:

SI- PRT/100

3x=x5t/100

300/5=60

Answer 2

Let that sum be P = x

Interest Rate, R = 5%

Time Period, T = ?

Simple Interest + Principal amount = 3x

( PRT / 100 ) + x = 3x

x(5)(T) / 100 = 3x – x

5x(T) = 2x × 100

5T = 200

T = 200 / 5

T = 40 years
