Conversion of fixed base index numbers into chain base index numbers

Year	Index
2008-09	134.8
2009-10	115.28
2010-11	115.57
2011-12	107.29
2012-13	109.91
2013-14	112.80
2014-15	106.24
2015-16	102.48

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	134.8	`=100`
2009-10	115.28	`(115.28)/(134.8)xx100=85.5193`
2010-11	115.57	`(115.57)/(115.28)xx100=100.2516`
2011-12	107.29	`(107.29)/(115.57)xx100=92.8355`
2012-13	109.91	`(109.91)/(107.29)xx100=102.442`
2013-14	112.8	`(112.8)/(109.91)xx100=102.6294`
2014-15	106.24	`(106.24)/(112.8)xx100=94.1844`
2015-16	102.48	`(102.48)/(106.24)xx100=96.4608`
