for eg my ans is 2.98 in numerical portion then obviously i would have to report the full ans as 2.98

but if my ans in the numerical portion comes out be an integer (for eg 7) then do i have to report 7 or 7.00

and in integer type ques do i have to report with decimal (7.00) or just the integer itself, are the both the ways fine?

and if anyone can provide the reference from an official source, it would be helpful

suggest me a good windows laptop (budget around 80k)

i need a sleek, good looking laptop, unlike the bulky gaming ones.

the laptop should have a good battery life and no graphics card would work well with me cause i dont like gaming.
