Hi Aayuva,
First off, a 740/Q49 is already an outstanding Score, so you can comfortably apply to any Business Schools that interest you. As such, a retest is not necessary. Depending on the Schools that you plan to apply to, you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement (and the more time that you have to act on that advice, the better).
There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admissio ... tants-124/There's certainly no harm in retaking the GMAT, but to find the missing points that you are looking for, you will have to nit-pick your prior CAT/mock performances in more detail. What types of Quant questions were you getting wrong - and more importantly, WHY were you getting them wrong? Were you doing work 'in your head' and making silly mistakes? Were you using approaches that took too long? etc. One of the interesting aspects of the GMAT is the most questions are written so that they can approached in more than one way - meaning that "your way" of approaching the Quant section might actually be leaving you open to making certain types of mistakes (and ending up with a Q49 instead of a Q51).
GMAT assassins aren't born, they're made,
