Hi All,

I have a very specific doubt, please help me understand this

Self created DS question and statement :
Is p divisible by 16?
a) when p is divided by 3, remainder is 1
b) when p is divided by 7, remainder is 2

I go on to deduce the following relation:
From a -
p = 3m+1 => p = 1,4,7 ...in increments of 3. ofcourse not sufficient.
From b -
p = 7n+2 => p = 2,9,16 ...in increments of 7. ofcourse not sufficient.
From a+b -
Next, the first common number in both the set is the required number.
because earlier i didnt write the entire list, for C i have to list all the elements. So ->
From a, we have list A = 1,4,7,10,13,16,19,22,25,28,31,34,37,40,43,46,49,52,55,58,61,...
From b, we have list B = 2,9,16,23,30,37,44,51,58,65,72,...
Okay, so now we have list C = common numbers from both = 16,37,58,...
As per the question, if I had stopped at 16 in list C, my answer would have been C. but because I checked for next numbers as well, I can definitely say answer is E.

Doubt :
Trend I notice here is:
37 - 16 = 21
58 - 16 = 21
I dont need to list down all the elements in list A and list B, as soon as I get first common number I can stop and add 3*7 (quotient from statement a and b) to get the next common number in list C. This will definitely help me save time.
Can you please confirm - Is difference same i.e. quotient 1 * quotient 2, each and every time?
If so, any logic underlying this?
