Let 1 Stand for "Any Given Period" and 2 Stand $\text { A) value of index at } 1=\frac{\text {absolute value at 1 }}{\text { absolute value at 2}}$

question 50

Short Answer

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

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

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

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

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