I think all the above answers are wrong.
Nearly all of Asia, Europe and Australia use the 220 - 240V,
50Hz system.
In India, it was adapted from the British Standard.
Voltage and Frequency are independent. Voltage is a compromise
between safety and efficient transport.
Higher Voltage needs less copper in wires and more insulation.
It was simply chosen arbitrarily as was practical to generate
at that time.
