Question : If $\left(x+\frac{1}{x}\right)=5$, and $x>1$, what is the value of $\left(x^8-\frac{1}{x^8}\right)?$
Option 1: $60605 \sqrt{21}$
Option 2: $60615 \sqrt{21}$
Option 3: $60705 \sqrt{21}$
Option 4: $60725 \sqrt{21}$
Correct Answer: $60605 \sqrt{21}$
Solution : Given: $\left(x+\frac{1}{x}\right)=5$--------------(i) Now, $\left(x^8-\frac{1}{x^8}\right)$ $=(x^4-\frac{1}{x^4})$$(x^4+\frac{1}{x^4})$ $=(x^2-\frac{1}{x^2})$$(x^2+\frac{1}{x^2})$$(x^4+\frac{1}{x^4})$ $= (x-\frac{1}{x})$$(x+\frac{1}{x})$$(x^2+\frac{1}{x^2})$$(x^4+\frac{1}{x^4})$----------(ii) Squaring equation (i), we get, $(x+\frac{1}{x})^2 = 5^2$ $⇒(x^2+\frac{1}{x^2}+2) = 25$ $⇒(x^2+\frac{1}{x^2}) = 23$-----------------(iii) Squaring equation (iii), we get, $(x^2+\frac{1}{x^2})^2 = 23^2$ $⇒(x^4+\frac{1}{x^4}+2) = 529$ $⇒(x^4+\frac{1}{x^4}) = 527$---------------(iv) Subtracting 2 on both sides of equation (iii),

Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 85, 84, 82, 79, 75, 70, 64, ?
Option 1: 59
Option 2: 57
Option 3: 82
Option 4: 76
Correct Answer: 57
Solution : Given: 85, 84, 82, 79, 75, 70, 64, ?
Subtract the natural number in increasing order from the previous number, to get the required missing number – 85 – 1 = 84; 84 – 2 = 82; 82 – 3 = 79; 79 – 4
Option 1: 3 – 9
Option 2: 5 – 25
Option 3: 7 – 49
