Twenty five sets of problems on Data Interpretation– one each for the DI sections of 25
CATALYST tests were prepared by the AMS research team. The DI section of each CATALYST
contained 50 questions of which exactly 35 questions were unique, i.e. they had not been used in
the DI section of any of the other 24 CATALYSTs. What could be the maximum possible number
of questions prepared for the DI sections of all the 25 CATALYSTs put together?
(Can anyone help by explaining the solution to this question)

Let me try to understand the question:
25 set of papers
50 in each with 35 distinct questions
Did I understand the question correctly?

If yes, the answer is: 35*25 = 875 questions.

n! = n*(n-1)!
1! = 1*(1-1)!
1! = 1*0!
As 1! = 1, hence 0! = 1

We know that n! = n(n-1)(n-2)(n-3).....3(2)(1) which means that
n! = n(n-1)!
Dividing both sides of the equation by n, we have
(n - 1)! = n!/n
Using this fact, we can check the following pattern.
4! = 5!/5 = {(5)(4)(3)(2)(1)}/5 = 24
3! = 4!/4 = {(4)(3)(2)(1)}/4 = 6
2! = 3!/3 = {(3)(2)(1)}/3 = 2
1! = 2!/2 = {(2)(1)}/2=1

Now, we go to 0!
0! = 1!/1 = 1

24×4 =96 + 4×10 = 136
current age = 24×7 = 168
hence children age = 32
2A + A - 2 = 32
A = 34/3 = 11.33 not possible
data is wrong as child can not be older than 10 years

here are 20 balls which are red, blue or green. If 7 balls are green and the sum of red balls and green balls is less than 13, at most how many red balls are there?

Reply Like? Yes | No

AMIT GARG 1 Month ago

7 balls are green
sum of red balls and green balls is less than 13
7 + R < 13
=> R < 6
Hence at most 5 red balls are there

Assuming repetition allowed - 1st Digit can be in 4 ways - Rest 4 can be in ways Hence 4*5*5*5*5 = 2500
Assuming repetition mot allowed = 4*4! = 4 * 24 = 96

Let q are the no of people
150=aq+r----(1)
270=bq+r----(2)
320=cq+r-----(3)
Eqn. 2 -1=q(b-a)=120
Eqn.3-2=q(c-b)=50
Eqn.3-1=q(c-a)=170
H.c.f of all these is 10
Hence the members are 10.
