With five seats, if P is at one end, O must be in the middle if N is next to O.

For l=2, the orbital type is d.

O is the father of Q, and since Q is the sister of R, O is also the father of R.

The variable resistor allows for adjustment to achieve balance in the bridge.

Substituting x=1 into the equation gives 1^2 + 3*1 + k = 0, hence k = -4.

Substituting x = 2 into the equation gives 2^2 - 3*2 + p = 0 => 4 - 6 + p = 0 => p = 2.

Substituting x=2 into the equation gives 2^2 - 4*2 + k = 0, thus k = 4.

Using the root, we substitute: 2^2 - 6*2 + k = 0 => 4 - 12 + k = 0 => k = 8.

Using Vieta's formulas, if one root is 3, the other root is 7 - 3 = 4. Thus, k = 3 * 4 = 12.

Using the root 2 in the equation: 2² - 6*2 + k = 0, we find k = 10.

Using the root, substitute x = 3: 3² - 7*3 + k = 0, which gives k = 10.

Using the root, substitute x = 3: 3² - 7*3 + k = 0, which gives k = 9.

Using the root, substitute x = 3: 3² - 7*3 + p = 0, which gives p = 6.

The sum of the roots is 3 + (-1) = 2, hence p = -2.

Substituting x = 2 into the equation gives 2^2 - 4*2 + k = 0, which simplifies to k = 4.

Using the root 3 in the equation: 3^2 - 7*3 + k = 0, we get k = 6.

Since Q = R and P > Q, it follows that P > R.

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.

R is across from P, and since Q is next to P, Q is not next to R.

Since R is opposite P and P is next to Q, Q is sitting next to R.

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 siblings since they share the same parents.

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

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

Since P is to the right of Q and R is to the left of Q, Q must be in the middle.

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.
