@Estallar12Yes,same method I used.@LogrhythmI think the method of putting a=b=c=d is better as it gives the maximum value and you can easily eliminate other options from it.You luckily got the answer,but would have consumed time had some random value appeared after calculation.
I would have done the same at runtime, actually had done using a=b=c=d=1 only....but then i thought to try with some other values.... 😃

provide the approach also...

@TONYMBA

Yaar,maths mein to 1st class se interest hai. Yahi to ek subject jismein shuro se top kiya hai.

But every1 says,rather than doing 2-3 books partially,better to pick 1 book and do it properly.

Coaching to sahi hai[Byju Sir is great],but material ka panga hai.

THinking of going with Arun Sharma only.

Arun Sharma of TIME Material for now. :)
Don't let the pressure take over. Quant will be fun. No issues. Work on your weaker areas for a couple on months. Get the phobia over and then roll. :)

Answer to that is 1


Put n=2,satisfies it.
