All the troops in the world are useless without leaders. India might have weapons, plenty of soldiers, nukes...
Pakistan would probably kick their ass
Pakistan has on the whole done fairly badly whenever they fought India, both strategically and tactically. Neither country has what could be called a first rate military but India is considerably stronger in nearly all categories and seems to be better trained and practiced. The military is also much less political with fewer competing agendas among the officer corps.
In a full scale war though the decisive factor could be the role of China.
Perhaps you could read up on the Indo-Pak wars of 1965,71 and 98. In 1971, India dismembered Pakistan and midwifed the birth of Bangladesh. In '98 - the Kargil conflict saw Indian forces evicting Pakistani troops bunkered significantly above them and still suffered fewer casualties.
Hence the Paki preference for Mumbai 2008 style fidayeen attacks.
