Question

in what time will the simple interest be 2 by 5 of the principal at 8% p a​

Answer 1

Step-by-step explanation:

Let principal be p

Simple interest = 2/5 p

R = 8 % p.a.

Time = Interest ×100/P × R

Time = (2/5p) × 100/p × 8

= 40/8

= 5 yrs

Answer 2

Answer:

5 years

Step-by-step explanation:

Let principal be x.

Therefore, simple interest=(2x)/5

We know, time=(100 × simple interest)/(principal×rate)

Therefore, (100×2x)/(x×8×5) years

= 5 years
