Question

Arun invested ₹ 48,000 for 1 year and 6 months at 15% per annum compounded annually. Find the total CI Arun gets.​

Answer 1

Answer:

11,340

Step-by-step explanation:

Principal=48000

Time=1.5 years

Rate=15%

Interest for 1st year=(48000×15×1)/100

Amount=48000+7200

=55200=Principal for 2nd year

Interest for 2nd year=(55200×15×0.5)/100

Amount=55200+4140

=59340

Compound Interest=59340-48000

=11,340

Hope this helps

Answer 2

Given ,

Arun invested Rs.$48,000$ for $1$ year $6$ months at $15$% per year compounded annually;

To find; Total Compound interest

Total amount invested $=48,000$

Time given $= 1 year 6 months$

Rate of Interest $=15$%

So here,

Interest paid for first year =(Invested amount×Rate of Interest × Year )/100

$=(48,000*15*1)/100$

$=72,0000/100 = 7,200$

Principal Amount ;$48,000+7,200=55,200$

Interest paid in half year= (Principal amount of first × Interest × year)/100

$=(55,200*15*0.5)/100$

$=4,14000/100=4,140$

Principal Amount :$55,200+4,140=59,340$

Now the compound interest is :$59,340-48,000=11,340$

Hence, CI is $11,340$
