L & T Infotech aptitude placement paper

Hi,

We had heard from our seniors that L & T Infotech visits our campus every year for campus placements. Ultimately our turn came and 80 students sat for the test. They chose 7 out of them - fortunately I am one among them.

For the benefit of my juniors and other candidates aspiring to work at L & T, I am posting some of the questions from aptitude test that were asked to us.

You can expect more similar questions from R S Agarwal.
