Answer 1

Answer:

13240

Step-by-step explanation:

Given, Principal = 40000, Rate = 10%, Time n = 18 months = (3/2) years.

∴ A = P(1 + r/100)²ⁿ

      = 40000(1 + 10/100)³

      = 40000(1 + 1/10)³

      = 40000(11/10)³

      = 53240.

∴ C.I = A - P

       = 53240 - 40000

       = 13240.

Therefore, Compound Interest = 13240.

Hope this helps!

Answer 2

Answer:

$\huge{\bold{\orange{SOLUTION}}}$

Principal=40000

Time= 15months = 1 -1/2 years

Rate=10%

Compounded half yearly

Compound Interest=

P(1 +r/2/100)^2×t -P

=40000×(1+5/100)^3 - 40000

=40000×(21/20 ×21/20 ×21/20 -1)

=40000 × (9261 -8000/ 8000)

=40000 ×1261/8000

=5×1261

=6305 rupees
