A、Because they are overloaded. B、Because they have not been adapted for the two new rupee notes. C、Because so many people are us

The Indian government has raised the limit on cash withdrawals following widespread public anger about the surprise (5)abolition of 500 ($7.60) and 1,000 rupee notes last week. Customers can now withdraw up to 2,500 rupees a day from cash machines, rather than 2,000, the finance ministry said. (6)Many cash machines are not working because they have not been adapted for the new 500 and 2,000 rupee notes. Long queues at many banks were making it difficult to make withdrawals. The abolition of the 500 and 1,000 rupee notes is intended to crack down on corruption and bring cash worth billions of dollars in unaccounted wealth back into the economy. (7)The two notes accounted for more than four-fifths of the currency in circulation and the change threatens to disrupt much of India’s cash-driven economy. The government also has  relaxed withdrawal limits from banks, removing the 10,000 rupees a day restriction and increasing the weekly limit by 4,000 rupees to 24,000.
