Question

in how much time will the interest be 3/5 of the principal at the rate if 4% per annum​

Answer 1

Answer:

time is 15 years

Step-by-step explanation:

we know that the simpleintrest formula is si=(p×t×r)/100--------- 1

then given thatinformation we have

let us take the principal amount be P="X"

then intrest become is SI=(3X)/5

rate of intrest is R=4%

then put the values in 1

(3X)/5=(X×T×4)/100

cancel X on both sides

3/5=(T×4)/100

3=4T/20

4T=60

T=15

then the time will be 15 yeara
