8. A bottle contains \( \frac{5}{7} \) litres of milk at price \( ₹ 10 \frac{1}{3} \) per litre. How much money did he earn? 10. The price of a chair is \( ₹ 25 \frac{1}{3} \) and that of a table is \( ₹ 975 \frac{1}{2} \). How much money is needed to buy 2 tables and 12 chairs? 11. If the price of 1 kg of rice is \( ₹ 45 \frac{7}{13} \), then what will be the price of \( 3 \frac{1}{4} \mathrm{~kg} \) of rice?

7 point What are the solutions to the equation \( 2 x^{2}-34=0 ? \) \( \{-\sqrt{34}, \sqrt{34}\} \) \( \{-\sqrt{17}, \sqrt{17}\} \) \( \{\sqrt{-17}, \sqrt{17}\} \) \( \{\sqrt{-34}, \sqrt{34}\} \)

\( \left. \begin{array} { l } { x = \frac { - b } { 2 a } } \\ { x = \frac { - ( - 2 ) } { 2 ( 1 ) } } \\ { x = \frac { 2 } { 2 } } \\ { x = \square } \end{array} \right. \)

What is the smaller solution to the equation \( 4 x^{2}+7 x-15=0 \) ? \( -\frac{5}{4} \) -3 \( \frac{4}{5} \)

\( \left\{ \begin{array} { l } { y ^ { 2 } - x ^ { 2 } + 2 x - 2 y \leq 0 } \\ { x ^ { 2 } = 4 x - y } \end{array} \right. \)
