-Let 1 stand for "any given period" and 2 stand for "base period." The formula of any index number can be written as: A) value of index at $1 = \frac { \text { relative value at } 1 } { \text {relative value at } 2} \times 100$


B) value of index at $1 = \frac { \text { absolute value at } 1 } { \text { absolute value at } 2}$


C) value of index at $1 = \frac { \text { relative value at } 1 } { \text { relative value at } 2}$

D) value of index at $1 = \frac { \text { absolute value at } 1 } { \text {absolute value at } 2} \times 100$

E) value of index at $1 = \frac { \text { absolute value at } 2 } { \text {absolute value at } 1} \times 100$
