Find the difference between the compound interest and the simple interest on rupees 30000 at 7% per .A for 3 years.

Answer»

ANSWER:

Principal=30,000 Rs.

C.I=4347 Rs.

Rate of interest=7 %

Amount=Principal+C.I

Amount=30,000+4347=34347Rs.

Let the TIME is T YEARS' then

⇒34347=30000(1+ 7/100)T

⇒34347=30000(107/100)T

⇒(107/100)T=34347/30000

⇒(107/100)T=11449/10000

⇒(107/100)T=(107/100)2

T=2years
