how to solve 100 questions in 60 minutes? eg.IBPS po exam

prepare smartly for any exam ..don't go behind numbers .one will say for eg. he/she has attended 90+ but what matters is your accuracy .at the end of the day one who gave 90+ with 60 or 70% may get failed and one who attended 70 odd with 100% accuracy passes the exam so it depends on how accurate you are !!!

No one has ever did that!!someone has to be a super man to do it..but from my experience i have seen person cracking upto 93 given the paper is very easy .Here mostly in PO one will attempt a exam in accordance to its toughness and the cut offs vary each year with respect to the toughness of that exam :)

Out of 21 tickets marked with numbers from 1 to 21, three are drawn at random. What is the probability that the numbers on them will be in AP?

ans -- 10/119 , maximum common difference can be 10 (tickes nos selected (1 , 11 , 21) ) and minimum common difference is 1 , comm difference ---- count of triplets with that common difference 1common diff ---- count of triplets with that common diff 1 19 2 17 ....... 10 1this will form an APTOTAL = 1+3.+5+7...........17+19 = 100possible ways -- 21C3ans -- 10/119

How to improve my verbal?

take mocks, identify the weak spots and practice!

practice practice practice!!give sectional mocks ..Try to understand and solve first and later try solving with a stipulated time!!!as u practice a lot your understanding level increase and time taken to solve will decrease

how to solve probability questions in sbi po exams

go to YouTube channel like current affairs funda study smart meritshine I m sure if you see all the videos from current affairs funda on probability your doubt would be clear

Practice with any standard book,like Arun Sharma.But don't spend so much time on Probability,there will be just one question from prob.

how may i solve seating arrangement,puzzles and inequalities

just practice a lot!!don't go with hard puzzles at first!!try some easier ones and try to understand the concept!!once you are strong in solving some easy ones go for some medium ques and tough ones...in exam don't worry about rough sheet getting used a lot...legibly jot the points down ..direct clues will be given so mark those st away..with those clues represented on ur rough sheet u can easily get the exact answer for puzzle ...if u dont have any direct clues and find the clues tougher its better to leave as these exams test ur smartness and not your ability to crack those...

books and material that i can consider

1/a + 1/b + 1/c = 3/4 how many ordered triplets of (a,b,c) are there??

Let us try to enumerate all the cases and count the number of triplets. Without loss of generality, we can assume that a <= b <= c.Therefore, the maximum value 'a' can take is 4.In the case where a = 2, 1/b + 1/c = 1/4 or c = 4*b/(4-b)The only possible natural number solutions to this are b = 5, c = 20; b = 6, c= 12 and b = c = 8In the case where a = 3, 1/b + 1/c = 5/12 or c = 12*b/(5b-12)The only possible natural number solutions to this are b = 3, c = 12 and b = 4, c= 6In the case where a = 4, 1/b + 1/c = 1/2 and the only possible case is a=b=c=4So, let us write all the possible triplets again (2,5,20); (2,6,12); (2,8,8); (3,3,12); (3,4,6) and (4,4,4)Hence, the number of triplets possible is 6 + 6 + 3 + 3 + 6 + 1 = 25

Just a ask here, do we take a,b,c as to always >0, there is a possibility of set having (1,-2,4) appears as well.

can anyone plz give me any links to clear my concepts regarding the topic time and distance

To clear your concepts of time and distance we suggest to take our cracku video series. Learning shortcuts and formulas can help you so much. With a lot of effort Cracku has made a pdf covering Formulas of time, speed and distance.
