Question

What is the time period for which rs. 8000 amounts to rs. 12000 at 20% p.A. Of simple interest?



select one:



a. 6 years



b. 4 years



c. 2.5 years



d. 3.25 years?

Answer 1

Option (c) is correct.

Explanation :

Principal (P)=Rs8000

Amount (A)= Rs12000

Rate of interest (R)=20%

Let the Time period = T years

Simple Interest (I) = A-P

= Rs12000 - Rs8000

=Rs4000

Now , we know that

(PTR)/100 = I

=> T = ( I × 100 )/( PR )

= ( 4000 × 100 )/( 8000 × 20 )

= 5/2 years

= 2.5years

Therefore,

T = 2.5 years
