(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.) (5, 4, 405) (7, 3, 500)
Option 1: (4, 1, 125)
Option 2: (3, 2, 145)
Option 3: (4, 5, 850)
Option 4: (5, 8, 789)
Correct Answer: (4, 1, 125)

Like, (5, 4, 405)→(5 + 4)2 × 5 = (9)2 × 5 = 81 × 5 = 405 (7, 3, 500)→ (7 + 3)2 × 5 = (10)2 × 5 = 100
Question : If $\frac{x^{2}-x+1}{x^{2}+x+1}=\frac{2}{3}$, then the value of $\left (x+\frac{1}{x} \right)$ is:
Option 1: 4
Option 2: 5
Option 3: 6
Option 4: 8
Correct Answer: 5
Solution : Let $( x+\frac{1}{x})$ be $y$. $\frac{x^{2}-x+1}{x^{2}+x+1}=\frac{2}{3}$ Taking $x$ common in both numerator and denominator, we get, $⇒\frac{x( x+\frac{1}{x}-1)}{x( x+\frac{1}{x}+1)}=\frac{2}{3}$ $⇒\frac{y-1}{y+1}=\frac{2}{3}$ $⇒3y-3=2y+2$ $\therefore y = x+\frac{1}{x} = 5$ Hence, the correct answer is 5.
