Solution:

Electronic Voting Machines (“EVM”) are being used in Indian General and State Elections to implement electronic voting in part from 1999 elections and recently in 2017 state elections held in five states across India.
An EVM can record a maximum of 3840 votes and can cater to a maximum of 64 candidates. There is provision for 16 candidates in a single balloting unit and up to a maximum of 4 units can be connected in parallel. The conventional ballot paper/box method of polling is used if the number of candidates exceeds 64.
