Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
A pineapple is classified as a multiple fruit. It develops from the fusion of many individual flowers within a cluster, called an inflorescence, into a single fruit. Unlike simple fruits that develop from a single ovary of a single flower, or aggregate fruits that develop from multiple ovaries within a single flower, multiple fruits like pineapples form from the fusion of multiple flowers.

Solution
A father decided to give 20% of his monthly income to his three children as their monthly allowance. The eldest child got 45% of the allowance and the youngest got 25%. How much was the father's monthly income if the second child got ₦ 3,000?
A
₦33,000
B
₦45,000
C
₦50,000
D
₦60,000
medium Difficulty
Verified Correct Answer: Option C
Step-by-Step Mathematical Solution
To find the father's monthly income, we follow these steps:
Let \( I \) = Father's monthly income, \( A \) = Total allowance.
The total allowance is given by:
\(A = 0.2 I\)
The second child receives 30% of the allowance:
\(0.3 A = 3000\)
Solving for \( A \):
\(A = \frac{3000}{0.3} = 10000\)
Father's Income:
Now, substituting \( A \) into the equation for income:
\(0.2 I = 10000 \implies I = \frac{10000}{0.2} = 50000\)
The father's monthly income is: ₦50,000

A

B
57
C
-57
D

medium Difficulty
Verified Correct Answer: Option B
Step-by-Step Mathematical Solution
To find the determinant of the matrix
\(P = \begin{pmatrix} 1 & 3 & 2 \\ 4 & 5 & -1 \\ -3 & 2 & 0 \end{pmatrix}\)
We use the formula:
\(\text{det}(P) = a(ei - fh) - b(di - fg) + c(dh - eg)\)
Substituting the values:
- \(a = 1\), \(b = 3\), \(c = 2\)
- \(d = 4\), \(e = 5\), \(f = -1\)
- \(g = -3\), \(h = 2\), \(i = 0\)
Calculating:
\(ei - fh = 5 \cdot 0 - (-1) \cdot 2 = 2,\)
\(di - fg = 4 \cdot 0 - (-1) \cdot -3 = -3,\)
\(dh - eg = 4 \cdot 2 - 5 \cdot -3 = 8 + 15 = 23.\)
Thus,
\(\text{det}(P) = 1 \cdot 2 - 3 \cdot (-3) + 2 \cdot 23 = 2 + 9 + 46 = 57\)
The determinant of matrix \( P \) is 57

medium Difficulty
Verified Correct Answer: Option A
Step-by-Step Mathematical Solution
Let the universal set be
\(U = \{1, 2, 3, 4, 5, 6, 7, 8, 9\}\)
and the set of prime factors of 30 be
\(P = \{2, 3, 5\}.\)
The complement of \( P \) is
\(P' = U - P = \{1, 4, 6, 7, 8, 9\}\)
Thus, the complement of \( P \) is {1, 4, 6, 7, 8, 9}.

A
1, 3
B
1, 2
C
2, 3
D
3, 2
medium Difficulty
Verified Correct Answer: Option A
Step-by-Step Mathematical Solution
To find the coordinates of the midpoint \( M \) of the line segment joining the points \( A(3, -4) \) and \( B(-1, 10) \), we use the midpoint formula:
\(M = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)\)
Substituting the coordinates of points \( A \) and \( B \):
- \( x_1 = 3 \)
- \( y_1 = -4 \)
- \( x_2 = -1 \)
- \( y_2 = 10 \)
Calculating the coordinates of the midpoint:
\(M = \left( \frac{3 + (-1)}{2}, \frac{-4 + 10}{2} \right) = \left( \frac{3 - 1}{2}, \frac{6}{2} \right) = \left( \frac{2}{2}, 3 \right) = (1, 3)\)
Thus, the coordinates of the midpoint are (1, 3).
