Answer 1

Answer:10 years

Step-by-step explanation:

here simple interest formula is prt/100

=400*5*1/100=20 rs

therefore simple interest is 20 Rs.

600-400=200

so here finding time formula= si*100/pr

=200*100/400*5= 10 therefore time is 10 years

[p=principal amount,r=rate,t=time,si=simple interest and * stands for multiplication] hope it helps ☺
