Question

what is the time period for which RS 8000 amounts to RS 12000 at 20 % p.a of simple interest ?​

Answer 1

Answer:

Step-by-step explanation:

Simple interest =principal *rate*time divided by 100

So, amount = interest +principal

Time =T

Therefore

8000*20*T/100 +8000=12000

1600*T+8000=12000

1600*T=12000-8000

T=4000/1600

T=2.5

Therefore time if 2.5 years
