nice book and helpful for student

Display ans also.....

Its a kind of good thing that they are providing with answers ...but the main purpose is not being served tthat is of studying digitally because the app doesnt work now since last 8 months. Also they havent updated the solutions after may 2016 . 3 papers are done after that . They should improve now .

Best thing for engineers! Great deed stupidsid!

good solutions!!!
