Explanation:

Raghuji was able to annex Odisha to his kingdom permanently as he successfully exploited the chaotic conditions prevailing in Bengal after the death of its governor Murshid Quli Khan in 1727. Constantly harassed by the Bhonsles, Odisha, Bengal and parts of Bihar were economically ruined. Alivardi Khan, the Nawab of Bengal made peace with Raghuji in 1751 ceding Cuttack (Odisha) up to the river Subarnarekha, and agreeing to pay Rs.1.2 million annually as the Chauth for Bengal and Bihar.
