My answer is D) Each statement is sufficient individually.
Total= Only P + Only C + Both
54= Only P + 18 + Both. We need to find both.
Statement 1) gives Only P = 12, hence we can find both- sufficient
Statement 2) gives C =42. C= Only C + both. we know only C hence we can find both- sufficient.

(1) Of the 54 participants, 12 did not sign up for ceramics.
(2) Of the 54 participants, 42 signed up for ceramics.

Ans. D - Each statement alone is sufficient.
The key is to understand that No ceramics, No photography will be 0.
Using 2 x 2 table, each statement alone will be sufficient.
Participants who both signed up for photography and ceramics will be 24.

The good thing in this question is that there the value of none is zero. In 2 set venn diagram we know there are 4 different areas, in this the 4 different area would be:
1. Only Ceramics
2. Only Photography
3. Both Ceramics and Photography
4. None, which is equal to zero as given
Given 18 participants did not sign up for photography then they must be included in Only ceramics.
So value of Only Ceramics = 18

S1: If 12 did not sign sign up for ceramics then they must be Only P and Only P= 12. And given, None = 0, Only ceramics = 18. We could easily get BOTH CERAMICS AND PHOTOGRAPHY to be: 54-18-12= 24
SUFFICIENT

S2: If 42 signed up for ceramics then we know, ONLY ceramics = 18(given), so the intersection part that is BOTH P and C would be equal to: 42-18= 24
SUFFICIENT

OA: D

Given,
54 = (only photography) + (only ceramics) + (both photography & ceramics)
Also,
18 = not photography
or, only ceramics = 18
To find: Number of Both?

Now,
Statement 1: Not ceramics = 12
or, Only photography = 12
We know, only ceramics = 18
Hence, 54 = 12 + 18 + both
Thus, Both = 24; Sufficient

Statement 2: Cermics = 42
or, Only ceramics + Both = 42
or, 18 + both = 42
Both = 24; Sufficient

Since both the Statements alone are sufficient.
Thus, correct answer is (D)

Total N = 54
n(P) = Number for Photography
n(C) = Number for ceramics
n(P&C) = Number for both Photography --> Need to find

N = n(P) + n(C) - n(P&C)

n(P^) = Number for not photography = 18 ==> Number for Photography n(P) = N - n(P^) = 54-18 = 36

54 = n(P) + n(C) -n(P&C)
n(P&C) = n(P) + N(C) - 54
n(P&C) = n(c) + 36 -54 = n(C)- 18

We will get the number for which ever option gives n(C)
1 - n(C^) = 12 ==> n(C) = 54-12 = 42 (Satisfies)
2 -n(C) = 42 Satisfies

Each option alone is sufficient

Total paticipants=54 and 18 didnt not sign up for photography ie. no of participants in only ceramic=18. Let only photography=x and both=y.
x+y+18=54, so x+y=36
Statement 1: x=12, so y=24--SUFFICIENT
Statement 2: x+18=42 so y=24--SUFFICIENT

Let P be no. of people signed up for Photography and C be for Ceramics and I be the no. of people signed up for both.
Given P+I+C = 54.--> eq1.
and C= 18--> eq2

Statement -1: given 12 did not sign up for ceramics. => P=12.
substituting in eq-1, I value I value is 24.

Statement -2 : Given I+C= 42.
From Eq-2 substituting C value in above equation, I=24.

Hence each option alone is sufficient

Bear with me while I try to explain in my terms :)

If we construct a Venn diagram:
We know that Ceramics (C)+ Photography (P) - Both(B) = 54
or C only + B + P Only = 54 ...... (i)

From the information we also know that
Only C = 18.... (ii)
So if we get P Only value then we are sorted:

From Statement 1:
if 12 didn't sign for Ceramics then Only P = 42.
Sufficient

Statement 2:
If 42 signed up for ceramics then P Only will be 54 - 42 which is equivalent to statement 1.
Sufficient.

IMO Ans is D.

The following things are mentioned in the question
Total= 54
18 did not sign up for Photography, so we can count them as the participants who enrolled for ceramics
So, C=18.


Now, looking at the statements

Statement 1,
It says 12 did not sign up for Ceramics
total ceramics group= 54-12= 42
Both= total ceramics- enrolled in ceramics only (C)
Both = 42-18= 24
Hence, this statement is sufficient.

Statement 2,

It says 42 participants enrolled in ceramics.
Both= total ceramics- ceramics only (C)
Both = 42-18=24
Hence, this statement is sufficient.

So, the answer is D, both statements are sufficient.

Using the tabular method, we can consider 54 total participants.
Participants part of No photography & No ceramic = 0

18 did not do photography => 36 did photography
Also, since No P & No C = 0 => C & No P = 18

Ask: Participants in photography & ceramic

I. 12 did not sign up for C -> 42 DID sign up for C -> (42-18) did both. Sufficient.
II. Essentially, the same information as above. Sufficient.

D.

Here is what is given in the question stem:

P union C = 54

18 did not sign up for Photography. This means only C is 18 and the entire P (all people who signed up for Photography) is 54 - 18 = 36

Statement 1- Of 54, 12 did not sign up for Ceramics. So, the entire C (all people who chose ceramics) = 54 - 12 = 42
If all who chose C is 42 and those who chose only C is 18, then those who chose both P and C is 42-18

Statement 2- Of 54, 42 signed up for C. If only C is 18, then both is 42-18

Both statements are sufficient on their own to find the number of people who choose both C and P

total = 54
given, 18 participants didnt signup for Photography...
54-18 = 36 participants photography ,
to find - both photography and ceramics -
total = P + C -( both P and C) + None
given all participants signed up for atleast one so None = 0
54 = P + C - ( both P and C )
54 = 36 + C - ( both P and C)
18 = C - (both P and C )
statement 1 : Out of 54 participants, 12 didnt signup for ceramics.
12 didnot signup for ceramics
so 54-12 = 42 signed up for ceramics
18 = 42 - ( both P and C)
both P and C = 24
sufficient
statement 2 : Out of 54 participants, 42 signed up for ceramics.
18 = 42 - ( both P and C )
both P and C = 24
sufficient
so Each statement alone is sufficient

Answer is D.
P + C + PC = 54, -P = 18
S1: -C = 18
PC + -C + -P = 54. can solve.
S2: C = 42
PC + -P = C. can solve. therefore D.

According to the stem since 18 did not sign up for photography, we can interpret it as 18 signed up for ONLY ceramic.

1. 12 did not sign up for ceramics, which means that 12 signed up for ONLY photography.
Thus, 56=12+18+Both
Both=24

2. If 42 signed up for ceramics and 18 signed up for ONLY ceramics
Both = 42-18 = 24

Hence the answer is D - Each statement is sufficient

This can be solved using a simple sets method

Note that 54 participants signed up for photography, ceramics or both. This implies that there was no one in the 'none' category

P~pTotal
Cx18
~C0
361854

We need the value of x

Statement 1 tells you the value of value ~C hence x = 36 -12 = 24 Hence sufficient

Statement 2 gives you the value of x + 18 = 42 Hence 42 -18 = 24 Hence sufficient
