As per 2005 Saachar committee report..
Muslims made up only 2.5 percent of the bureaucracy, even though they constituted almost 12 percent of the population.
According to CNN IBN’s Minority Report,
of India’s one million soldiers only 3 percent are Muslims, or roughly 29,000 soldiers in all. And if the troops serving in the Jammu & Kashmir Light Infantry (JAK LI), are subtracted (50 percent of whom are Muslim troops), that percentage is much lower. With only 29,000 fit for the army out of 150 million Muslims in the country, the ambiguous silence of the government tends to validate the suspicion of discrimination.
