Question

8000 for 3 years at 15% per annum.​

Answer 1

Answer:

FINDING SIMPLE INTEREST,

SI=₹3600

AMOUNT=₹11600

FINDING COMPOUND INTEREST,

CI=₹4167

AMOUNT=₹12167

Step-by-step explanation:

PRICIPAL=₹8000

TIME= 3 YEARS

RATE%=15%

SO,

FINDING SIMPLE INTEREST,

SI=PRT/100

  =(8000*15*3)/100

  =80*45

  =₹3600

SI=₹3600

AMOUNT=₹3600+₹8000

               =₹11600

NOW,

FINDING COMPOUND INTEREST,

A=P(1+R/100)^N

  =8000(1+15/100)^3

  =8000(115/100)^3

  =(8000*115*115*115)/100*100*100

  =₹12167

AMOUNT=₹12167

CI=₹12167-₹8000

   =₹4167

I HOPE YOU UNDERSTOOD THE QUESTION

Answer 2

Answer:

CI = 4167

Step-by-step explanation:

HERE:

P = 8000

R = 15%

T = 3 years

A = p(1+R/100)T

A = 8000[1+15/100]³

= 8000(1.15)³

A = 12167

CI = A-P

= 12167-8000

Therefore, CI = 4167
