An art gallery is creating a display featuring four abstract art paintings and three scenery paintings. The only abstract art paintings considered are A, B, C, D, E, and F; the only scenery paintings considered are J, K, L, M, and N.

• If A is displayed, then neither B nor L can be displayed.
• B is displayed only if D is shown.
• C cannot be displayed unless J is displayed.
• K can only be displayed if K is displayed.
• If L is displayed, then M must be displayed.
• N cannot be displayed unless D is not displayed.

 If F is displayed, which one of the following must be true?
A. A is not displayed.
B. B is not displayed.
C. K is not displayed.
D. L is displayed.

If both B and E are displayed, then which one of the following CANNOT be a partial list of items displayed?
A. C, D, E
B. C, J, M
C. C, D, M
D. C, J, K

Each of the following could be displayed together EXCEPT:
A. B and K
B. B and F
C. B and M
D. E and F

If B is displayed, which one of the following is a list of items that could also be displayed?
A. A, M, N
B. C, E, F
C. C, L, M
D. E, J, M

Explanation

We are given:

• Each pill contains = 0.2 grams of medicine
• Total available medicine = 1 kilogram = 1000 grams

Step 1: Calculate the Number of Pills

Number of pills= Total medicine/Medicine per pill​

=1000/0.2​

=1000×10​/2=5000

Explanation

Step 1: Define Work Rates

• Danish can type 100 form letters in 6 hours, so his work rate is: $$frac{100}{6} = frac{50}{3} text{ letters per hour}$$
• Together, Danish and Muneeb complete 100 letters in 4 hours, so their combined work rate is: $$frac{100}{4} = 25 text{ letters per hour}$$

Step 2: Define Muneeb's Work Rate

• Let Muneeb's work rate be $m$ (letters per hour).
  $$50/3+m=25$$
• Solve for $m$:
  m=25−50/3​ $$m = frac{75}{3} - frac{50}{3} = frac{25}{3} text{ letters per hour}$$

Step 3: Time Taken by Muneeb Alone

• Muneeb alone needs to type 100 letters, so the time required is: $$frac{100}{frac{25}{3}} = 100 times frac{3}{25} = 12 text{ hours}$$

Explanation

Based on the prefixes listed, the correct answer is D. S, as it makes valid words like "Send," "Soft," "Stone," and "Scare."

Explanation

If the boy has completed 75% of his 12-mile trip:

Completed distance = 75% of 12 = (75/100) × 12 = 9 miles

Distance left = 12 - 9 = 3 miles

Explanation

Setup:

Six products (U, V, W, X, Y, and Z) are to be placed on six stalls in the “Pakistan Cultural Exhibition,” numbered 1 through 6 from left to right. The following conditions apply:

1. U cannot be immediately to the left or immediately to the right of V.
2. W must be immediately to the left of X.
3. Z cannot be on stall 6

Which of the following products CANNOT be placed on stall 1?

Options: A. U
B. V
C. W
D. X

Correct Answer: C
Reason: Since W must be immediately to the left of X, W cannot be placed on stall 1 because there would be no space for X on the left.

If X is placed on stall 3, W must be placed on which stall?

Options:

A. 2
B. 4
C. 5
D. 6

Correct Answer: A
Reason: W must be immediately to the left of X, so if X is on stall 3, W must be on stall 2.

If U is placed on stall 5, which of the following products must be placed on stall 6?

Options:

A. V
B. W
C. X
D. Y

Correct Answer: D
Reason: Z cannot be on stall 6 (as per the rules). W and X must be adjacent, so they cannot fit in 5 and 6. Y is the only option left for stall 6.

If Z is placed on stall 3, immediately to the right of X, which of the following products must be placed on stall 5?

Options:

A. V
B. W
C. X
D. Y

Correct Answer: D
Reason:Since Z is in stall 3, and it's immediately to the right of X, this means:

X must be in stall 2

W must be in stall 1 (since W is to the left of X).

Now, stalls 4, 5, and 6 remain for U, V, and Y.

If U is placed in stall 5, V cannot be adjacent (i.e., stall 4 or 6).

This means Y must be placed on stall 5 to allow V and U to be separated.

Explanation

Statement I, which indicates that taxes on all businesses have increased, is likely to lead to Statement II, where many small businesses will have to close their operations due to the higher tax burden.

Explanation

Based on the statements:

• Since some tools are useless things and all useless things are trash, it follows that some tools must be trash.
• Conclusion I cannot be confirmed as we do not know if any hammers fall into the category of tools that are trash.
• Conclusion III is false because not all useless things are tools.

Thus, only II is necessarily true.

Explanation

• P is 2 (the smallest non-negative even number).
• Q is 9 (the largest odd number).
• R is 5.

So, (P + Q + R) = 2 + 9 + 5 = 16.
