Step-by-step explanation:
Given:
Principal = Rs. 1200
Rate of interest = 25%
To find:
The time in which the interest will became equal to the principal.
Solution:
We have,



If interest is equal to the principal, then



The formula for amount is:

Substituting
in the above formula, we get



Taking log on both sides, we get

![[\because \log a^b=b\log a]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog%20a%5Eb%3Db%5Clog%20a%5D)


Therefore, the interest will became equal to the principal in about 3.11 years.
Yes, the point near 10 is an outlier because it is a variable far away from the others, it may effect your answer (if needed).
