P is heavier than Q is a direct statement from the given information.

Q must be first since P is after Q and R is before P.

P is the aunt of R as well, since R and Q are siblings.

R is the daughter of P as she is the sister of Q, who is the child of P.

P is the grandfather of Q, and since R is the father of Q, P is R's father.

P and R are both children of Q, making R the sister of P.

Since P ≤ Q and Q < R, it follows that P < R.

Profits should be divided in accordance with their capital contributions, which are 60% for A and 40% for B.

In the absence of any other agreement, profits are typically divided in the ratio of capital contributions.

Profits should be divided in accordance with their capital contributions, so A receives 60% and B receives 40%.

Despite the capital contribution, the partners agreed to split profits equally, hence 50% to each.

Profits should be divided in accordance with their capital contributions, hence 60% to A and 40% to B.

If Product B's sales in Q3 were 327 units, a 10% increase would result in approximately 360 units.

The expected growth rate from Q3 (320 units) to Q4 (400 units) is 25%.

Sales in Q2 were 200 + (25% of 200) = 200 + 50 = 250 units.

The sales in Q2 were 390 units, which is a 30% increase from Q1.

A relation is a function if every element in the domain (set A) maps to exactly one element in the codomain. Here, 1 maps to 2, and 2 maps to 3, but 3 has no mapping, so R is not a function.

A relation R is reflexive if every element in set A is related to itself. Since R contains (1, 1), (2, 2), and (3, 3), R is reflexive.

A relation is symmetric if for every (a, b) in R, (b, a) is also in R. Since R only contains pairs of the form (a, a), it is symmetric.

A relation R is transitive if whenever (a, b) ∈ R and (b, c) ∈ R, then (a, c) must also be in R. Here, (1, 2) and (2, 3) are in R, but (1, 3) is not, so R is not transitive.

R is not reflexive as (1,1), (2,2), (3,3) are not in R. It is symmetric as (2,3) implies (3,2) is not in R. It is transitive as (1,2) and (2,3) implies (1,3) is not in R. Thus, R is not all of the above.

R is reflexive because it contains all pairs (a, a) and symmetric because (1,2) implies (2,1).

R is not a partial order because it is not transitive; (1,2) and (2,2) do not imply (1,2).

R is reflexive and symmetric, but not transitive. Thus, both 1 and 2 are true.

R is neither reflexive, symmetric, nor transitive as it does not satisfy any of the properties.

R is not symmetric as (b,c) does not imply (c,b) is in R. It is reflexive and transitive.

R is neither reflexive, symmetric, nor transitive.

Since R is between S and T, and U is opposite S, T must be next to U.

Since R is to the left of S, R is also to the right of S, making R the one sitting to the right of S.

Using the balance condition R1/R2 = R3/R4, we find R4 = (R2 * R3) / R1 = (15 * 5) / 10 = 7.5Ω.
