To solve this problem, we need to determine the share of profits Dinesh receives in the firm after being admitted as a partner.
Aman, Boman, and Chetan originally shared profits in the ratio of 5:3:2. This means:
It is given that Aman surrendered \(\frac{1}{5}\)th of his share to Dinesh. Aman's share before surrendering is \(\frac{1}{2}\).
To find out what fraction of this \(\frac{1}{2}\) Aman gives to Dinesh, we calculate \(\frac{1}{5}\)th of \(\frac{1}{2}\):
\[ \frac{1}{5} \times \frac{1}{2} = \frac{1}{10} \]
Therefore, Dinesh is admitted with a \(\frac{1}{10}\) share in the profits of the firm. The correct answer is \(\frac{1}{10}\).
If \[ A = \begin{bmatrix} 1 & 2 & 0 \\ -2 & -1 & -2 \\ 0 & -1 & 1 \end{bmatrix} \] then find \( A^{-1} \). Hence, solve the system of linear equations: \[ x - 2y = 10, \] \[ 2x - y - z = 8, \] \[ -2y + z = 7. \]
