Hi guys,
Please help me with the below problem.I need the solution as well as the approach.
When a number 'N' is divided by a proper divisor 'D',then it leaves a remainder of 14 and if thrice of that number i.e. 3N is divided by the same divisor D,the remainder comes out to be 8.Again if 4N is divided by D,the remainder will be
a)35 b)22 c)5 d)cant be determined
One more problem,
A number when divided by 5 gives a number which is 8 more than the remainder obtained on dividing the same number by 34.Such a least possible number is
a)175 b)75 c)680 d)does not exist
When a natural number divided by a certain divisor,we get 15 as the remainder.But when 10 times the same number is divided by the same divisor,we get 6 as the remainder.The maximum possible number of such divisors is
a)6 b)7 c)15 d)cant be determined
Note: Solution & approach required
A certain number 'C' when divided by N1,it leaves a remainder of 13 and when it is divided by N2,it leaves a remainder of 1,where N1 and N2 are positive integers.Then the value of N1+N2 is ,if N1/N2=5/4
a)36 b)27 c)54 d)cant be determined uniquely
Set S is formed by selecting some of the numbers from the first 110 natural numbers such that the HCF of any two nos in the set is the same. If every pair of nos of set S has to be relatively prime ans set S has the maximum no of elements possible, then in how many ways can the set S be selected?
1) 64 2) 96 3) 72 4)108
The remainder of (32^32^32)/7 is ???
Hello everyone,
I am completely scared of CAT 2015 because Its been more than a month since I prepared . I got held up in a college project. Now I'm not able to resume my preparation because of the fear.

HI Puys and Pirls,
Wanted to ask how you attempt the QADI section. IT always happens that I am unable to even see let alone attempt all the questions . :
@Highway66 @scrabbler @psycho.munna @Nipun008 ....and others too
- Attempting only the questions you are familiar or which are easier and if time left go back for more attempts
- Sequentially from 1-50
- The GP approach: Round 1 Round 2 Round 3 approach
- Or some other method in which case pls elaborate
