Explanation:

Mahalanobis model was an integral part of India’s second five-year plan (1956-1961). The zest of this model was to build up a domestic consumption goods sector and to modify the pattern of industrial development. After the failure of third five-year plan because of Indo-Sino war, Indo-Pakistan war and a severe drought in 1965 the Government had to finally announce a plan holiday in 1966-1969. The fifth five-year plan was rejected by the Janta party government and sixth five-year plan was introduced. It was further rejected by the Indian National Congress in 1980 and a new plan was again proposed by them. Now the rolling plan came to the rescue which had essence of all the three previous plans.
