Question

4.4. Find out amount and CI on Rs 12000 in 3 years when the rates of interest for
successive year are 10 %, 12% and 15 % respectively.​

Answer 1

Answer:

AMOUNT = ₹17001.60

CI= ₹5001.60

Step-by-step explanation:

FOR THE FIRST YEAR,

P=₹12000

R%=10%

T=1 YEAR

SO,

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

  =12000(1+10/100)^1

  =12000(110/100)

  =120*110

  =13200

FOR THE SECOND YEAR,

P=₹13200

R%=12%

T=1 YEAR

SO,

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

  =13200(1+12/100)^1

  =13200(112/100)

  =132*112

  =14784

FOR THE THIRD YEAR,

P=₹14784

R%=15%

T=1 YEAR

SO,

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

 =14784(1+15/100)^1

 =14784(115/100)

 =₹17001.60

SO,

AMOUNT=₹17001.60

CI=A-P

  =₹17001.60-₹12000

  =₹5001.60
