Question

the time in which simple intrest will be 2/5 of principal at rate 8%p.a. is​

Answer 1

Answer:

Let the simple interest be 2/5 of principle at 8 % per annum.

Simple interest = Principal(P) × Rate(R) × Time(T)/100

                            PRT/100

T = (S.I × 100)/(P × R)

((2/5)P × 100)/(P × 8)

200/40

5 years

Thus, the time is 5 years.
