CPI is the one which is closely related to the consumers as most of the goods in WPI are very basic goods and they only indicate the inflation in terms of raw materials and capital goods but the actual inflation is felt more by the end users which is recorded more accurately in CPI. One more thing is Service sector provides most employment in our country than manufacturing and since Service sector is not included in WPI it is difficult to measure the inflation in case of service sector which is not in case of CPI and hence the change
But one disadvantage in using CPI for measuring inflation is that, most of the consumer side sale is not even recorded like not getting any bill and most of the service sector industries are in unorganized way and hence there will be lot of leakage. But in case of countries like US credit cards are being used in all walk of life even for purchase of a bus ticket so the leakage will be less there and will be more accurate. Hence the CPI inflation is not fit for India right now as we have more unorganized sector contribution in the service sector

Vignesh ur rite but we need to change unorganised to a organised sector rather than changing the whole process who thought before 1 year that they need to give thumb impression for ration and DMT ... soo we can change positively

Clearly government has also agreed for CPI since they want to show results of inflation to country people at the end of 2021. Since India is not an export oriented country therefore CPI targeting will give an good picture to outsiders also.
no sir..we can't use wooden needle

sir this might be because magnetic compass needle will deflect when electric current is passed via coil but this is not a case with wooden needle as it is a bad conductor of electricity and do not contain any charge

kuki moving charge mai current produce hoga or wo current perpendicular direction mai m. f. generate krega to compas deflect karega agr niddle wood ki hui to bhi deflect karegi
