sab yaha jhooth bolm rahe hai, agar himmat hai toh apni real marksheet post karoo

Aap jhootha naam rakh rahe hai! Aap sunnydeol hai, sunnyleony nahin. Himmat aur dhai kilo ki haath ki baat sirf sunnydeol karte hai.

@sstarrr black dp? Protesting something? :D

Not really. What is here to protest? Wanted to change DP , and when nothing struck then went for black background.

Also something related to how I have been feeling in recent days. Not so great , so reflects my state these days.

Similarly for this question as well first we need to put e in the last so the initial 4alphabet abab similarly last four alphabet eded are there and the for the rest of the sequence count the number of b d and c you will find b 3 times c 3 times and similarly d 3 times hence we need to have b c d all one times hence answer would be b c d e.

Why won’t it be c? ababa, bcbcb, and so on?

Yar yeh bta do koi please

Which institute's answer keys tallies closest to the actual result for y'all? Especially for CSAT.


Giving my first attempt this year, wanted to attempt the 2020 CSAT paper.. I see the divergence that's being talked about even in questions that look really really straightforward. 

Thanks!!

C hi hona chahiye. You're right.

Option C looks right. It forms a pattern. Option d doesn't. 

The trick mentioned above fails because here a and e are not equivalent. On completing the sequence there are 3 a's and 2 e's. The sequence is cyclical so the number of letters will match only if we take it to zazaz. Then there will be 5 letters each. 

The process in such questions is to 

1) count the number of letters in the phrase. The factors of that number are the possible length of the repeating units. Here there are 20 letters. So possible units can be of length 2,4,5 or 10. 2 and 10 can be ignored. So it's either 4 or 5

2) substitute the options and see if there are repeating units of the needed length forming. 

This should in most cases give the right answer.

Last year 96, this year 89.80

I know sky is the limit for target scores in prelims and it would be a failure’s trait to always hover around margins, but not able to write Mains because of one damn question year by year is such a bummer.
