Hi Kavanashree,

What exactly do you mean by passing marks here? I am taking the liberty of making an assumption since your question is not clear on that aspect.

90+ percentile is a must if you are aiming for top colleges and I guess you are doing the same. I will give you a section-wise breakup of marks needed to achieve the above-mentioned percentile.

LANGUAGE COMPREHENSION: 18-19

MATHS: 13-14

DA: 16-17

CRITICAL REASONING: 17-18

PS - You need a 97+ percentile to get calls from the best institutes. Also, the above-mentioned marks are the basic minimum you need to get to score a 90+ percentile. So, tweak them according to your intelligence. Please remember that your accuracy is what will make or break your game. 

Valuation Process - Total Marks - 200

The scaled score is out of 800. So scoring is done on a maximum possible marks of 160.

Hope this helps.
