Sir I wrote mains this time And I wrote pre too this time I prepare csat mostly form your videos It really helped me during exam even in making guess your lecture helped if i passed this time you will be the one of the greatest reasons
You are the only one in the whole CSAT market who has done Q58 (Venn Diagram one) correctly. Rest are just guessing without even making the venn diagram that we cannot answer the question using the 2nd statement. Good analysis. Thanks
No Sir has drawn the Venn Diagram Correctly, but There will be people who will take both coffee and milk, let say "y". I am stressing on this quesion because it will decide my this year's mains Attempt. Plz correct me sir if I am wrong Plz sir.
@@sahemasiddiqui2018 Hi Sahema. You are correct that there can be people who will take both coffee and milk say y, but these 'y' people are already counted in the 45 people who are drinking coffee but not tea. If you add y in 120 + x, there will be double counting of 'y' people. Still you want to put 'y' in the intersection of coffee and milk you can do that, but end result will be same. Let me show you. If you put intersection of coffee and milk = y , then only coffee people will be (45 - y), right? Now total number of people in the party = (Only Tea) + (Tea and Coffee) + (Only Coffee) + (COffee and milk) + (Only Milk) = 60 + 15 + (45 - y) + (y) + (x) = 120 + x So how many people drink both coffee and milk (y) does not matter. PS : My mains is also dependent on this question
@@AkshayKumar-ir7fi Does not make any sense. There is nothing wrong in this question. Just because many coaching institutes are not able to solve this question you think UPSC will cancel this? If you want to send representation then send for 78 gm question because an important point is missing in the question
@@AgroKrishi Yes you may be right. But that is not what is asked. It is asked how many attended the party...choose anything between 0 and 45 for the value of y...number of people attending the party will always be 150 Had the question been "how many drink both milk and coffee?" then we had to use statement 1 also...but not for this question.
In question no. 44 answer should be B instead of C. Because two half-yearly interest are always greater than interest calculated annually. Sir check that question once again.
Hi Tarun, thanks for your query, but here question is saying “ if amount is same in both the cases, then what is the relation of rate of interest in both the cases?
there are 3 cases where T can be true 1) both r and s are false 2) r is true and s is false 3) r is false and s is true. So if we assume the second condition that r is true and we check if p is true then both q and s are true so both p and r cannot be true at a time if t is true. And similarly, if we consider p is false then there are 3 conditions 1)both q and s are false 2) q is true and s is false 3) q is false and s is true. so if we consider q is false and s is true, then to T become true R must be false. Hope its clear
Sir. I couldnot think in the level as you do problem solving in the exam hall. Watching the video right now makes me realize there are lot more dimensions to a topic. ❤. It hurts.

Unit digit has to multiplied the times of power u will simply get the unit digit no need of these steps it is 2^5 = 32 and unit digit is 2. As power has unit digit 5 after multiplication
There is formula for that.. If X^a*Y^b=(a+1) (b+1) .. Where a&b are exponents of X and Y respectively. Here after taking lcm of 96 we get 2*2*2*2*2*3 So 2^5*3^1=(5+1)(1+1) =12
*2:11:11** wrong answer..... Milk + coffee also possible or MILK only also possible - not sure and question not saying exactly... answer should be D ....file representation*
Sir does ur course have lessons on every topic for an absolute beginner in math? Or only for studnets with basic knowledge in maths ur courses are suitable?
Sir, in the 49th question it is asked on 10^10th day and not after 10^10th day. And since today is 1st day and it is Sunday, we should also include sunday while adding remainder (odd days). Then answer will be wednesday. We can confirm it by applying same logic to smaller values . For ex. It will be Tuesday on 10th day even if remainder of (10÷7) is 3. Sir Please correct me if this is wrong.
@@sarkaripath3132 if it's Tuesday for remainder=3 , then it will definitely be wednesday for remainder=4. That example for 10th day was just to confirm which you can crosscheck from calendar.
8.Answer ,we can calculate like this also: Last digit is 2 .and we multiple all powers the answer is 945 . Here last digit is 5 that means 2*2*2*2*2 the answer is 32 Unit digit is 2 in 32 so the answer is 2❤
sir in the 58th qn when you took the sum of all person who drink tea,coffe and milk,why did you avoid the portion which include person who drink milk and coffee?you just took milk only portion but not the common portion for milk and coffee?
in question no. 9, if we take ABC to be 690 and DEF to be 421 then the condition of the question is satisfied but the sum of all digits is 22. And in one more case 760+351= 1111, here sum of all digits is 22. No options matches this
Slight correction from official Answer key in Q49. The answer is given Wednesday. (UPSC is very confusing and i feel this answer is debatable) But regardless, you're the best and I've benefited immensely from your videos. A big Thank You sir.
hi sir, can u clarify my doubt please. question nor 36. statement 2- what if first add 5 colours except white that is 180-54= 126 then adding 1 white ball, it becomes 127.. so it also contains atleast one ball of each colour right!! 126 can be a smallest number.. and 167 can be a larger number..(according to ur explanation)
Sir questions number 58,You are telling only one of condition out of Three, there are 3 situations for person taking Milk, first one is that All 50 milk taking person takes Coffee, Second case is No One Taking Milk takes Coffee,Third case is Some are taking both Milk and coffee and you are solving this third condition,What About First 2 conditions where All Milk Taking person Takes coffee and No One Taking Milk takes Coffee???

Hi Ankur , thanks for your query. In Data sufficiency questions, if we are reading second statement, we should read that alone. I mean we should forget about first statement.
