On the Richter scale, which measures the total amount of energy released during an earthquake, a reading of x-1 indicates one-tenth the released energy as is indicated by a reading of x. On that scale, the frequency corresponding to a reading of 7 is how many times as great as the frequency corresponding to a reading of 5? Options: A) 10^2 B) 10^3 C) 10^4 D) 10^5 E) 10^6
If Richter scale reading goes from X-1 to X it will be 10   if Richter scale reading goes from 5 to 6 it will be 10   Similarly if Richter scale reading goes from 6 to 7 it will be 10   so it will from 5 to 7 i.e 6,7 = 10*10 = 10^2   10^2nswer is 10^2
