According to Nature News (http://www.nature.com/news/2010/100610/full/news.2010.292.html) , melt water supplies 1.5 times other sources to the Indus and 0.25 times other sources to the Brahmaputra and glacial melt water constitutes 40% of the total melt water with the balance coming from seasonal snowfall.

The melt water percentage is 1.5/2.5 = 60% for the Indus and 0.25/1.25 = 20% for the Brahmaputra. The glacial melt water portion of the total melt water is 40% for both rivers. Therefore, the glacial melt water percentage is 0.6*0.4 = 24% for the Indus and 0.2*0.4 = 8% for the Brahmaputra.
