There isn't a consensus on his year of birth. While I haven't come across 1920 as a candidate, opinion seems to be divided between 1928 and 1930. 

 * 'Screen' obituary citing 1930 
 * 'The Pioneer' cites 1928 
 * 'The Indian Express' chooses the "1920's" 
 * 'The Music Magazine' goes with 1928 
 * Pakistan's 'Dawn' chooses 1930
