Conversion of chain base index numbers into fixed 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 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	134.8	`=134.8`
2009-10	115.28	`(115.28xx134.8)/100=155.3974`
2010-11	115.57	`(115.57xx155.3974)/100=179.5928`
2011-12	107.29	`(107.29xx179.5928)/100=192.6851`
2012-13	109.91	`(109.91xx192.6851)/100=211.7802`
2013-14	112.8	`(112.8xx211.7802)/100=238.8881`
2014-15	106.24	`(106.24xx238.8881)/100=253.7947`
2015-16	102.48	`(102.48xx253.7947)/100=260.0888`
