    Select Question Language :


    A mobile software has been developed which consists of four switches, each of these switches can be in either the ON or the OFF
    positions. A switch when pressed will toggle its position i.e. if an ON switch is pressed it will become OFF and vice-versa.

    If you can press any two switches, not necessarily adjacent, how many configurations are possible?

    Options :-

    1. 2
    2. 4
    3. 8
    4. 16
