Solution:

(a) Successive change in index = - 2 - 1 +

2/100

\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;

\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\ = - 2.98 %

[- ve sign shows decrease in value]
Therefore, Required percentage increase =

{100\a}/{100-\a

(where a = 2.98 %)

\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;= {100 ×2.98}/{100 - 2.98
