Question

find the amount and the compound interest when the interest is compounded annually principal =18000,Time=2years,rate=15/1/2% per annum​

Answer 1

Answer:

Step-by-step explanation:

Given - Principal = 18000

Rate of interest = 15.5%

Years = 2

Amount = Principal (1 + R / 100) raised to N

= 18000 (1 + 15.5 / 100) raised to 2

= 18000 x 115.5 / 100 x 115.5 / 100

= 18 x 115.5 x 115.5 / 10

= 240124.5 / 10

= 24012.45

Therefore the amount will be rs. 24012.45

Answer 2

Answer:

Amount is 24012.45, and Compound interest is 6012.45

Step-by-step explanation:

Now see how to do

Principal = 18000

Rate = 15 1/2 as 31/2

Year(n) = 2

$amount \: = principle \: (1 \times \frac{r}{100 \: } )n$

Amount = 18000 (1 + 31/200)2

18000×(231/200)2

18000 × 231/200 × 231/200

= 9 × 231 × 231/20

= 480259/20 = ₹ 24012.45

Amount = 24012.45

CI = a - p

= ₹24012.45 - 18000

=6012.45

CI = 6012.45

Hope this helps you

Be safe and be happy
