Question

If the principle becomes 3 times in 15 years then the rate of simple interest per annum.
​

Answer 1

Step-by-step explanation:

let the principal be x

then the Amount be 3x

Si = Amount - principal

Si= 3x-x

Si= 2x

Time = 15year

we know that

Si= (P×R×T)/100

2x= (x×R×15)/100

200x= 15Rx

200= 15R

200/15= R

40/3= R

13⅓= R
