Question : Directions: In the following question, find the odd number pair from the given alternatives.
Option 1: 85 : 136
Option 2: 34 : 85
Option 3: 102 : 153
Option 4: 63 : 162
Correct Answer: 63 : 162
Solution : Let's check the options – First option: 85 : 136→136 – 85 = 51 Second option: 34 : 85→85 – 34 = 51 Third option: 102 : 153→153 – 102 = 51 Fourth option: 63 : 162→162 – 63 = 99 ≠ 51
Question : If $2x-\frac{1}{2x}=5,x\neq0$, then the value of $(x^2+\frac{1}{16x^2}-2)$is:
Option 1: $\frac{19}{4}$
Option 2: $\frac{23}{4}$
Option 3: $\frac{27}{4}$
Option 4: $\frac{31}{4}$
Correct Answer: $\frac{19}{4}$
Solution : Given; $2x-\frac{1}{2x}=5,x\neq0$ Dividing both sides by 2, we get $x-\frac{1}{4x}=\frac{5}{2}$ Now, squaring both sides, we get $(x^2+\frac{1}{16x^2}-2×x×\frac{1}{4x})=\frac{25}{4}$ ⇒$(x^2+\frac{1}{16x^2})=\frac{25}{4}+\frac{1}{2}$ ⇒$(x^2+\frac{1}{16x^2})=\frac{27}{4}$ ⇒$(x^2+\frac{1}{16x^2}-2)=\frac{27}{4}-2$ $\therefore (x^2+\frac{1}{16x^2}-2)=\frac{19}{4}$ Hence, the correct answer is $\frac{19}{4}$.
