Question

The minimum number of zeros in an upper triangular matrix will be ______.

विकल्प

• ${\displaystyle \frac{n(n-1)}{2}}$

• ${\displaystyle \frac{n(n+1)}{2}}$

• ${\displaystyle \frac{2n(n-1)}{2}}$

• None of these

Answer 1

The minimum number of zeros in an upper triangular matrix will be ${\displaystyle \underline{\frac{n(n-1)}{2}}}$.

Explanation:

Minimum no. of zeros in a triangular matrix is given by ${\displaystyle \frac{n(n-1)}{2}}$ where n is order of matrix.
