CBSE BOARD X, asked by ayushsingh77786, 5 months ago

Biswa decided to save money for a trip. He was<br />checking some investment options for saving,<br />but his friend Kalia suggested to check if he is<br />interested in compound interest. Biswa found a<br />bank that offers 6% compound interest<br />calculated on a half-yearly basis. To know in<br />detail, Biswa planned to deposit Rs. 20000 each<br />on 1st of January and 1st of July of that same<br />year. But Biswa is not that great at Math! Can<br />you help him know, what amount he would have<br />gained through interest by the end of the year?​ ​

Given :-

  • Principal = Rs.20000 .
  • Rate = 6% compounded half yearly .
  • Time = 1 year .

To find :-

  • CI = ?

Solution :-

we know that, when rate is compounded half yearly,

  • Time = 2 times = 1 * 2 = 2 years.
  • Rate = Half = 6 / 2 = 3% per annum .
  • Amount = P[1 + (R/100)]^time .

putting values we get,

→ A = 20000[1 + (3/100)]²

→ A = 20000 * (103/100)²

→ A = (20000 * 103 * 103) / 100 * 100

→ A = Rs.21,218

therefore,

→ CI = A - P

→ CI = 21218 - 20000

→ CI = Rs.1218 (Ans.)

Hence, Biswas gained Rs.1218 by the end of the year.
