Explanation:

The office of the Deputy Chief Minister (CM) is not mentioned in the Constitution of India. Article 163 says that there shall be a Council of Ministers with the Chief Minister as the head to aid and advise the Governor in the exercise of his functions, except in so far as he is required to exercise his functions in his discretion. Unlike the posts of chief minister and cabinet ministers, that of a deputy chief minister is not a constitutional post. Hence statement 1 is correct. • The post of Deputy CM is equivalent to the rank of a cabinet minister (in the state) and enjoys the pay and perks that a cabinet minister is entitled to. Hence statement 2 is correct. • The deputy CM does not enjoy any specific financial power. He also holds the same financial powers as other cabinet ministers. Even for his own portfolio, the Deputy CM has to take approval of the chief minister for any expenditure over and above the allocated budget. Hence, statement 3 is correct.
