Sorry i could not understand log. Could you explain it in simpler terms? I am in class 7.
The question was
if a sum of money doubles in 8 yrs, in how many years will it triple itself?Is the answer 16? If it is please tell me how to show the workings. I understood the concept but cannot express it.This is a simple interest sum.
