I want to use font in image "attached" but don't know what is it's name so that I can search over internet.
Tell me if anybody knows the answer.
It's very similar to MB Picture House — clues are the M not touching the baseline; points at vertices; low cross-bar on the E; high centre on the S.
Negative indicators are: that particular cut of the font doesn't have lower-case letters; the cross-bar of G may not be an identical match; the cross-bar of A may be a little high.
[Aside: feasibility is spelled wrongly in the image.]
Please look at the NEUTRA family fonts, probably this family contains one of the fonts which is close to the font in the question.
Identifont to the rescue!
EDIT: Identifont is a website which lets you identify fonts by asking a series of questions. It even has a function to base the questions on a restricted set of characters (as is the case here, we don't know what other letters look like). The URL i provided already has the graphs' subset setup for you. Answer the questions, and you'll be given a list of fonts that meet your demands.
