Question : In a railway track, two rails are joined end to end with a gap in between them because:
Option 1: steel can be saved
Option 2: accidents due to contraction in winter can be avoided
Option 3: air - gaps are necessary for bearing the weight of running train
Option 4: accidents due to expansion in summer can be avoided
Correct Answer: accidents due to expansion in summer can be avoided
Solution : The correct option is accidents due to expansion in summer can be avoided.
Metal, including steel, expands and contracts with temperature changes. Leaving a small gap between the rails allows them to expand in hot weather and
Question : $\text { If } x^2+y^2+z^2=x y+y z+z x \text { and } x=1 \text {, then find the value of } \frac{10 x^4+5 y^4+7 z^4}{13 x^2 y^2+6 y^2 z^2+3 z^2 x^2}$.
Option 1: 2
Option 2: 0
Option 3: –1
Option 4: 1
Correct Answer: 1
Solution : $x^2+y^2+z^2=x y+y z+z x$ $⇒\frac{1}{2}[(x-y)^2+(y-z)^2+(z-x)^2] = 0$ $⇒ x= y, y=z,$ and $z=x$ As $x =1$, so $y=z=1$ So, $\frac{10 x^4+5 y^4+7 z^4}{13 x^2 y^2+6 y^2 z^2+3 z^2 x^2}$ $= \frac{10(1)^4+5(1)^4+7(1)^4}{13(1)^2(1)^2+6(1)^2(1)^2+3(1)^2(1)^2}$ $=\frac{22}{22}$ $=1$ Hence, the correct answer is 1.
Question : Select the misspelt word.
Option 1: Release
Option 2: Arrivel
Option 3: Plight

Question : The value of $\frac{\left(\cos 9^{\circ}+\sin 81^{\circ}\right)\left(\sec 9^{\circ}+{\operatorname{cosec}} \;81^{\circ}\right)}{{\operatorname{cosec}}^2 \;71^{\circ}+\cos ^2 15^{\circ}-\tan ^2 19^{\circ}+\cos ^2 75^{\circ}} $ is:
Option 1: 1
Option 2: 4
Option 3: 5
Option 4: 2
Correct Answer: 2
Solution : Given: $\frac{\left(\cos 9^{\circ}+\sin 81^{\circ}\right)\left(\sec 9^{\circ}+{\operatorname{cosec}} \;81^{\circ}\right)}{{\operatorname{cosec}}^2 \;71^{\circ}+\cos ^2 15^{\circ}-\tan ^2 19^{\circ}+\cos ^2 75^{\circ}} $ $= \frac{\left(\cos 9^{\circ}+\sin (90^\circ - 9^{\circ})\right)\left(\sec 9^{\circ}+\operatorname{cosec}(90^\circ - 9^{\circ})\right)}{{\operatorname{cosec}}^2 \;(90^\circ- 19^{\circ})+\cos ^2 15^{\circ}-\tan ^2 19^{\circ}+\cos ^2 (90^\circ - 75^{\circ})} $ $= \frac{\left(\cos 9^{\circ}+\cos 9^{\circ}\right)\left(\sec 9^{\circ}+\sec 9^{\circ}\right)}{\sec^2 19^{\circ}+\cos ^2 15^{\circ}-\tan ^2 19^{\circ}+\sin
