Bir kııtasiyeci tanesini \( (x+3) \) liradan aldığı kalemlerin ta- nesini \( (2 x-1) \) liradan satıyor. Kırtasiyecinin bu kalemlerden 6 tane satması duru- munda elde edeceğı kârı lira cinsinden veren cebirsel ifade aşağıdakilerden hangisidir? \( \begin{array}{ll}\text { A) } 6 x+4 & \text { B) } 6 x-4 \\ \text { C) } 6 x-12 & \text { D) } 6 x-24\end{array} \)

What is the greatest natural number \( x \), so that it leaves remainders 8 and 20 when 308 and 200 are divided by \( \times \) respectively.

48. If \( a=3-\sqrt{2} \) and \( b=\frac{a+1}{a-1} \) what is the value of \( b \)

(3) If the point \( (x-5,7-x) \) lies in the second quadrant, then \( x=- \) \( \begin{array}{lll}\text { (a) } 9 & \text { (b) } 3 & \text { (c) } 7\end{array} \)

100. यदि \( 5^{\sqrt[3]{x}}+12^{\sqrt[3]{x}}=13^{\sqrt[3]{x}} \) है, तो \( x \) का मान है: If \( 5^{\sqrt[3]{x}}+12^{\sqrt[3]{x}}=13^{\sqrt[3]{x}} \), then the value of \( x \) is:

\( \begin{array}{ll}\text { 1. } 3 x=2 x+18 & \text { 2. } \\ \text { 4. } 4 z+3=6+2 z & \text { 5. } \\ \text { 7. } x=\frac{4}{5}(x+10) & \text { 8. }\end{array} \)
