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

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

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

Year	Chain base index number	Fixed base index number
2008-09	126	`=126`
2009-10	130.8	`(130.8xx126)/100=164.808`
2010-11	143.3	`(143.3xx164.808)/100=236.1699`
2011-12	156.1	`(156.1xx236.1699)/100=368.6612`
2012-13	167.6	`(167.6xx368.6612)/100=617.8761`
2013-14	177.6	`(177.6xx617.8761)/100=1097.348`
2014-15	181.2	`(181.2xx1097.348)/100=1988.3945`
2015-16	177.2	`(177.2xx1988.3945)/100=3523.435`
