Conversion of fixed base index numbers into chain base index numbers

Year	Index
2008-09	126
2009-10	130.8
2010-11	143.3
2011-12	156.1
2012-13	167.6
2013-14	177.6
2014-15	181.2
2015-16	177.2

Solution:
Conversion of fixed base index numbers into chain base index numbers :

Since base year is not mentioned here, So we will take 100 as the chain base index number for first year

`"Chain base index number"=("Fixed base index number of current year")/("Fixed base index number of preceding year") xx 100`

Year	Fixed base index number	Chain base index number
2008-09	126	`=100`
2009-10	130.8	`(130.8)/(126)xx100=103.8095`
2010-11	143.3	`(143.3)/(130.8)xx100=109.5566`
2011-12	156.1	`(156.1)/(143.3)xx100=108.9323`
2012-13	167.6	`(167.6)/(156.1)xx100=107.3671`
2013-14	177.6	`(177.6)/(167.6)xx100=105.9666`
2014-15	181.2	`(181.2)/(177.6)xx100=102.027`
2015-16	177.2	`(177.2)/(181.2)xx100=97.7925`
