Q. If a global organization has 12 member countries and each country contributes equally to a fund of $240 million, how much does each country contribute? (2023)
A.
$15 million
B.
$20 million
C.
$25 million
D.
$30 million
Solution
Contribution per country = Total fund / Number of countries = $240 million / 12 = $20 million.
Q. If a government scheme allocates a budget of ₹50,000 for education and it is to be distributed equally among 5 schools, how much will each school receive?
Q. If A is a 2x2 matrix and B is a 2x2 matrix, what is the order of the product AB? (2019)
A.
2x2
B.
2x3
C.
3x2
D.
3x3
Solution
The order of the product of two matrices is determined by the outer dimensions. Since both A and B are 2x2 matrices, their product AB will also be a 2x2 matrix.
Q. If A is a 2x2 matrix and B is a 2x3 matrix, what is the order of the product AB? (2019)
A.
2x2
B.
2x3
C.
3x2
D.
2x5
Solution
The order of the product of two matrices is determined by the outer dimensions. Here, A (2x2) and B (2x3) can be multiplied, resulting in a matrix of order 2x3.
Q. If A is a 3x3 matrix and B is a 3x3 matrix, what is the maximum number of non-zero elements in A + B? (2021)
A.
9
B.
6
C.
3
D.
0
Solution
The maximum number of non-zero elements in the sum of two matrices occurs when all elements of both matrices are non-zero. Therefore, A + B can have a maximum of 9 non-zero elements.
Q. If A is a 3x3 matrix and B is a 3x3 matrix, what is the maximum order of the resultant matrix when A is multiplied by B? (2022)
A.
3x3
B.
6x6
C.
9x9
D.
3x6
Solution
The order of the resultant matrix when two matrices are multiplied is determined by the outer dimensions. Here, both A and B are 3x3, so the product AB is also 3x3.
