Question : Simplify:
${\frac{x^4-2 x^2+1}{x^2-2 x+1}}$

Option 1: $x^2-2 x+1$

Option 2: $x^2+2 x+2$

Option 3: $x^2+2 x+1$

Option 4: $x^2+x+1$

Team Careers360 24th Jan, 2024

Correct Answer: $x^2+2 x+1$


Solution : ${\frac{x^4-2 x^2+1}{x^2-2 x+1}}$ .

$=\frac{(x+1)^2(x-1)^2}{(x-1)^2}$
$= (x+1)^2$
$= x^2+2x + 1$
Hence, the correct answer is $ x^2+2x +1$.

Question : The ratio of the sum of the salaries of A and B to the difference between their salaries is 11 : 1, and the ratio of the sum of the salaries of B and C to the difference between their salaries is also 11 : 1. If A's salary is the highest and C's is the lowest, then what is B's salary (in Rs.) given that the total of all their salaries is Rs. 1,82,000?

Option 1: Rs. 72,000

Option 2: Rs. 60,000

Option 3: Rs. 50,000

Option 4: Rs. 86,400

Team Careers360 24th Jan, 2024

Correct Answer: Rs. 60,000


Solution : Given: The salaries of A, B, and C are:
$\frac{\text{A+B}}{\text{A–B}}=\frac{11}{1}$
And, $\frac{\text{B+C}}{\text{B–C}}=\frac{11}{1}$
Applying componendo and dividendo, we get:
$\frac{\text{A}}{\text{B}}=\frac{12}{10}=\frac{6}{5}$
And, $\frac{\text{B}}{\text{C}}=\frac{12}{10}=\frac{6}{5}$
$\therefore$ A : B : C = 36 : 30 : 25
Let $\text{A = 36x; B = 30x; C = 25x}$.

Question : In how many years will Rs. 2,000 yield Rs. 662 as a compound interest at 10% per annum compounded annually?

Option 1: 3

Option 2: 2

Option 3: 4

Option 4: 5

Team Careers360 25th Jan, 2024

Correct Answer: 3


Solution : Rate, R = 10%
Principal amount, P = Rs. 2,000
Compound interest, CI = Rs. 662
When compounded annually, Compound interest after n years = $P[(1+\frac{R}{100})^{n} –1)]$
⇒ $662 = 2000[(1+\frac{10}{100})^{n} –1)]$
⇒ $2662 = 2000(1+\frac{10}{100})^{n})$
⇒ $1.331= (1.1)^{n}$
⇒ $n = 3$ years
Hence,
