On a scale that measures the intensity of a certain phenomenon, a reading of n+1 corresponds to an intensity that is 10 times the intensity corresponding to a reading of n. On that scale, the intensity corresponding to a reading of 8 is how much times as great as the intensity corresponding to a reading of 3?

A) 5
B) 50
C) 10^5
D) 5^10
E) 8^10-3^10

Could not get to the answer, could you explain your workings, will post OA later.

I get C

every reading it increases 10 fold.
Assuming :
1 -1
2 -10
3-100
4 - 10^3
5 - 10^4

8 - 10^ 7

Question asks how many times as great: 10^5

A) 5 B) 50 C) 10^5 D) 5^10 E) 8^10-3^10

LET THE INTENISTY OF (N+1) = 10X
// // // // // (N) = X

READING THREE INTENISTY IS = X
4 = 10X
5 = 10*10X

8 = 10^5X

THUS IT IS C IE 10^5 AS MUCH AS THE INTENISTY AT 3
