खण्ड 🗕 अ
SECTION - A
प्रश्न संख्या 1 से 10 तक प्रत्येक प्रश्न 1 अंक का है । Question numbers 1 to 10 carry 1 mark each.
- सभी शून्येतर वास्तविक संख्याओं के समुच्चय में, माना <math>*</math> एक द्विआधारी संक्रिया है, जो सभी <math>a,b\in R-\{0\}</math> के लिए <math>a * b = \frac{ab}{5}</math> द्वारा प्रदत्त है । यदि <math>2 * (x * 5) = 10</math> है, तो x का मान ज्ञात कीजिए । Let * be a binary operation, on the set of all non-zero real numbers, given by a * b = <math>\frac{ab}{5}</math> for all a, <math>b \in R - \{0\}</math>. Find the value of x, given that <math>2 * (x * 5) = 10</math>.
- यदि <math>\sin \left( \sin^{-1} \frac{1}{5} + \cos^{-1} x \right) = 1</math> है, तो x का मान ज्ञात कीजिए । If <math>\sin\left(\sin^{-1}\frac{1}{5} + \cos^{-1}x\right) = 1</math>, then find the value of x.
- <math>a = 2 \begin{bmatrix} 3 & 4 \\ 5 & x \end{bmatrix} + \begin{bmatrix} 1 & y \\ 0 & 1 \end{bmatrix} = \begin{bmatrix} 7 & 0 \\ 10 & 5 \end{bmatrix} = \begin{bmatrix} 8, & 1 \\ 10 & 5 \end{bmatrix}</math> <math>\begin{bmatrix} 1, & 1 \\ 10, & 1 \end{bmatrix}</math> <math>\begin{bmatrix} 1, & 1 \\ 10, & 1 \end{bmatrix}</math> <math>\begin{bmatrix} 1, & 1 \\ 10, & 1 \end{bmatrix}</math> <math>\begin{bmatrix} 1, & 1 \\ 10, & 1 \end{bmatrix}</math> If <math>2 \begin{vmatrix} 3 & 4 \\ 5 & r \end{vmatrix} + \begin{vmatrix} 1 & y \\ 0 & 1 \end{vmatrix} = \begin{vmatrix} 7 & 0 \\ 10 & 5 \end{vmatrix}</math>, find (x - y).
