Answer 2

Answer:

Step-by-step explanation:

there is a direct formula to find the principal if the simple interest, time and rate of interest is given i.e.  (I*100)  / R*T    where i stands for interest , r for rate and t for time respectively.

so the principal is

time = 8months= 8/12 years= 2/3 years

(20000*100)/12.5*2/3

= (20000*100*10*3)/125*2

=4000*10*3

=120000

hence the principal is 120000 rupees.
