The product of two numbers '231' and 'ABA' is 'BA4AA' in a certain base system (where base is less than 10), where A and B are distinct digits. What is the base of that system?
There are three cities: A, B and C. Each of these cities is connected with the other two cities by at least one direct road. If a traveller wants to go from one city (origin) to another city (destination), she can do so either by traversing a road connecting the two cities directly, or by traversing two roads, the first connecting the origin to the third city and the second connecting the third city to the destination. In all there are 33 routes from A to B (including those via C). Similarly, there are 23 routes from B to C (including those via A).
How many roads are there from A to C directly?
1) 10
2) 3
3) 5
4) 6
5) 12
6) CAT me aa hi nahi sakta aisa question. Skip
—
the possibilities for the number of routes from A to C is either one of {1,4,9}.

can v solve this using differentiation ?? plz help .
Any one help me with the funda of functions (types and no of functions etc )
and any e material related with modulus based problems ..
thanx in advance
First 100 natural numbers in the decimal system are converted to base 6 and their product is found. Find the number of consecutive zeros at the end of the product as counted in the base 6 system.

radius of circle D is 8..find AB???
Pls see the attachd figure...
How many distinct line can nct line can be drawn through 8 point exactly 4 of which are collinear and remaining 4 are also collinear
puyz plss help
refer to the attachd fig
MN is parallel to AB, MP=rt 56, PN=12, radius of circle=???

assume for simplicity that N people, all born in april (a month of 30 days), are collected in a room. consider the event of atleast two people in the room being born on the same date of month, even if in different years, e.g 1980 and 1985. what is the smallest N so that the probablity of this event exceeds 0.5 ?? Approach pls....
