Let a,b and c be the fractions such that ` a prec b prec c`. If c is divided by a, the result is `9/2`, which exceeds b by `23/6`. If `a+b+c = 19/12`, then (2a+b-c) will be equal to :
मान लीजिये कि a, b और c ऐसे भिन्न है कि ` a prec b prec c` है| यदि c को a से विभाजित किया जाए, तो परिणाम `9/2` आता है जो b से `23/6` अधिक है | यदि `a+b+c =19/12` है, तो (2a+b-c) का मान क्या होगा ?

A

`1/3`

B

`1/2`

C

`1/4`

D

`1/12`
