Answer:
C 210
Step-by-step explanation:
To solve this, First we must take 42/3, Since it equals 14, we take 15x14 and find 210
(edit: to solve for Kim's missing values, you do the same with 2 and 32)
3 x 10^-5.
Explanation: You move the decimal point 5 places to the right, hence it <span>becomes 3 x 10 to the power of NEGATIVE 5 (moved 5 places right)</span>
Given:
Amount = Rs. 34476
Rate of compound interest = 4%
Time =
years
To find:
The principal value.
Solution:
Formula for amount is
![A=P\left(1+\dfrac{r}{100}\right)^t](https://tex.z-dn.net/?f=A%3DP%5Cleft%281%2B%5Cdfrac%7Br%7D%7B100%7D%5Cright%29%5Et)
Where, P is principal value, r is rate of interest and t is time in years.
Putting the given values, we get
![34476=P\left(1+\dfrac{4}{100}\right)^{2.5}](https://tex.z-dn.net/?f=34476%3DP%5Cleft%281%2B%5Cdfrac%7B4%7D%7B100%7D%5Cright%29%5E%7B2.5%7D)
![34476=P\left(1+0.04\right)^{2.5}](https://tex.z-dn.net/?f=34476%3DP%5Cleft%281%2B0.04%5Cright%29%5E%7B2.5%7D)
![34476=P\left(1.04\right)^{2.5}](https://tex.z-dn.net/?f=34476%3DP%5Cleft%281.04%5Cright%29%5E%7B2.5%7D)
![\dfrac{34476}{\left(1.04\right)^{2.5}}=P](https://tex.z-dn.net/?f=%5Cdfrac%7B34476%7D%7B%5Cleft%281.04%5Cright%29%5E%7B2.5%7D%7D%3DP)
Now,
![P=31256.0090](https://tex.z-dn.net/?f=P%3D31256.0090)
![P\approx 31256](https://tex.z-dn.net/?f=P%5Capprox%2031256)
Therefore, the value of sum or principal value is Rs.31256.
