lbvjy [14]

<h2>Question:-</h2>

  • Find the compound interest when
  • principal =2000
  • rate =20%per annum
  • and time 3 years.

<h2>To find:-</h2>

  • Compound interest

<h2>Given:-</h2>

  • Principal = Rs.2,000
  • Rate = 20%
  • Time = 3 years.

<h2>Solution:-</h2>

⇒A = P (1 + \dfrac{R}{100} )^{n}

=2000 (1 + \dfrac{20}{100})^{3}

 = 2000 ( 1 + \dfrac{1}{5} )^{3}

 = 2000 (\dfrac{6}{5}) ^{3}

 = 2000 \times\dfrac{6}{5} \times \dfrac{6}{5} \times \dfrac{6}{5}

= 16 × 6 × 6 × 6

⇒A = Rs.3456

⇒CI = A - P

⇒CI = 3456 - 2000

⇒CI = Rs.1456

Answer:-

·Compound interest is Rs.1456.

I need the answer please
Veseljchak [2.6K]
The trick to solving this problem is to know and remember that the sum of all the interior angles of a triangle is always 180 degrees.

Thus, (6x+1) + (5x-17) + (9x-24) = 180.

20x = -40, so x = -2 (answer)
