The last two digit of the multiplication of 1*3*5*7.........97*99 will be

Pv Aaditya

1*3*5*...*99 = 25k
25k mod 100 = 25 if k mod 4 = 1
25k mod 100 = 75 if k mod 4 = 3
In this case, 1*3*...*23*27*...*99 mod 4 = 1*-1*1*-1*...*1 (25 pairs) = -1 = 3
So, remainder = 75

How much practice of DI on an average is required

Sayali Kale
0 Likes Posted 1 year, 3 months ago

Hi Satwik,

The amount of practice that is needed for DI or any other section varies from person to person. A good way of figuring out how much percentage of time you need to allot for a particular section is by analysing how well you are performing in that section in the mock tests. In DI, there as some sets that are straight-forward like sets based on line charts, bar charts etc. that are generally calculation intensive. If you are good with calculations in general, you need not spend a lot of time on these type of sets. Then there are other types of sets like games and tournaments, balancing quantities etc. that are more logic based and less calculation based. If you find that these are troubling you in mocks, you need to spend more time on these type of sets. On the whole, it is a good idea to solve at least 2-3 DI sets everyday in the last two months.

Check out a few of our DI tests here:

The analysis of recently held CBSE exam shows that Chennai Zone, Delhi Zone and Ajmer Zone have performed the best. The average marks of the Ajmer Zone & Delhi Zone put together is 71%. The average marks of Chennai Zone & Delhi Zone put together is 76% and the average marks of Chennai Zone & Ajmer Zone put together is 79%. What is the range of the average marks of all the three zones ( N ) put together. a) 71%<N<78% b) 70.5%<N<77.5% c) 73.5%<N<77.5% d) 73%<N<79%

Pv Aaditya

Average of Ajmer = A; number of students in Ajmer = a
Average of Delhi = D; number of students in Delhi = d
Average of Chennai = C; number of students in Chennai = c
(aA+dD)/(a+d) = 71;(cC+dD)/(c+d) = 76;(cC+aA)/(c+a) = 79;
Cross-multiplying and adding the equations,
2Aa + 2Dd + 2Cc = 150a + 147d + 155c
Because a, d and c are independent, equate the like terms
So, 2A = 150 => A = 75; 2C = 155 => C = 77.5; 2D = 147 => D = 73.5
So, the maximum and minimum values of (aA+dD+cC)/(a+d+c) are 77.5 and 73.5 respectively
73.5 < N < 77.5

Statemnt1 : No pen is yellow. 2: some pencils are yellow. conclu: some pencils r not pens. kindly explain by univrsal or particular affirmative method given as in TIME material. thanks

Shreya Reddy

The first statement can be written as "No yellow is pen"
The second statement says "Some pencils are yellow"
So some pencils(which are yellow) are not pens.

Beides practice , how do I improve my accuracy in verbal?

Sayali Kale
0 Likes Posted 1 year, 3 months ago

Hi Anjum,

Improvement in accuracy/percentile takes time and consistent hard work. We advise students to spend at least a couple of hours every day working on their areas of weakness. The most important section in Verbal is RC - proficiency in all other areas of Verbal can be improved if one improves in RC. To improve in RC, initially make a small summary of the RC that contains the gist of the article. After writing the summary, go back and read the article to see if you missed any points. Follow this method consistently for a couple of weeks, and you will find yourself improving in RC.

Apart from this, concentrate on Grammar questions because this is an area where the accuracy can be close to 100%. Most importantly, every time you get a question wrong, do a thorough analysis of where you went wrong in the thought process. Try to incorporate these learnings into your next test/question.

Take a look at these links for practise questions in Verbal Ability:

Sir which material best for g k to ibps eaxm???

Maruti Konduri

Hi Kiran, remember that IBPS PO prelims has no GK component. So, I would recommend you to focus on Quant, Reasoning and English for the coming 2 weeks.
Once, you are done with the prelims, visit websites like http://www.gkedge.com/index on a daily basis. You can also checkout our Banking Quotient which contains more than 100 free Banking Tests (with many based on GK). The link is https://cracku.in/banking/quotient

I want to bell the CAT in one month. Is that enough time for preparation?

Maruti Konduri

Hi Satya,

Focus on solving as many Mocks as possible in the remaining two months to CAT. Spend quality time analyzing your performance in Mocks and try to improve your scores. Ideally at least three months of serious preparation is needed to crack CAT, but focus on giving it your best shot with the remaining time at hand.

Regards,

Maruti

Amar and Balu start running from the same point in a circular track with speeds 8 kmph and 10 kmph respectively. Find the number of distinct points at which Amar and Balu meet on the track .

Sai Kiran K

The number of distinct points if they are running in the same direction is x-y if the speeds are in the ratio x:y respectively where x:y ratio is in the lowest possible form. Hence, the 8:10 would be expressed as 4:5 and the number of distinct points would be 5-4= 1 point.

How can i improve my Reading Comprehension skills?

Vikas Bansal

In the verbal section of IBPS-PO, reading comprehensions, para-jumbles, para-completion and sentence correction questions are asked. As banking paper is coming soon, try to solve previous year banking papers and as many mocks as possible and learn from the mistakes. At the end duration, this practice is very efficient. All the best.
