Question : If the sum of squares of two real numbers is 12 and the product of the numbers is 4, find the difference between the numbers.

Option 1: 4

Option 2: 8

Option 3: 1

Option 4: 2

Team Careers360 25th Jan, 2024

Correct Answer: 2


Solution : Given:
The sum of squares of two numbers = 12
Product of the numbers = 4
Let the numbers be $a$ and $b$.
⇒ $a^2+b^2=12$ and $ab = 4$
We know, $(a-b)^2=a^2+b^2-2ab$
⇒ $(a-b)^2=12-2\times4$
⇒ $(a-b)^2=12-8$
⇒ $(a-b)^2=4$
⇒ $a-b=\sqrt4=2$
Hence, the correct answer is

Question : If $A+\frac{1}{A}=-1$, then find the value of $\frac{{A}^6+{A}^3-1}{{~A}^9+{A}^3-1}$.

Option 1: 0

Option 2: –1

Option 3: 2

Option 4: 1

Team Careers360 25th Jan, 2024

Correct Answer: 1


Solution : $A+\frac{1}{A}=-1$ ⇒ $A^2+A+1=0$
Now,
$A^3-1^3 = (A-1) (A^2+A+1)$ 
⇒$A^3-1 = (A-1)\times 0$ 
⇒$A^3-1 =0$ 
⇒$A^3=1$
So, $\frac{{A}^6+{A}^3-1}{{~A}^9+{A}^3-1}$
$=\frac{{(A^3)}^2+{A}^3-1}{{(A^3)}^3+{A}^3-1}$
$=\frac{1^2+1-1}{1^3+1-1}$
$= 1$
Hence, the correct answer is 1.

Question : A person lent Rs. 10,000 to B for 3 years and Rs. 6,000 to C for 4 years on Simple interest at the same rate of interest and received Rs. 5,400 in all from both of them as interest. What is the rate of interest (in percent)?

Option 1: 10

Option 2: 12.5

Option 3: 15

Option 4: 20

Team Careers360 25th Jan, 2024

Correct Answer: 10


Solution : Let the rate be $r$.
We know, Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$
So, interest from B = $\frac{10000×3×r}{100}=300r$
Also, interest from C = $\frac{6000×4×r}{100}=240r$
According to the question,
⇒ $300r+240r = 5400$
⇒ $540r = 5400$
$\therefore r =10\%$
Hence, the correct

Question : Simplify the given expression. $\frac{x^3+y^3+z^3-3 x y z}{(x-y)^2+(y-z)^2+(z-x)^2}$

Option 1: $\frac{1}{3}(x+y+z)$

Option 2: $(x+y+z)$

Option 3: $\frac{1}{4}(x+y+z)$

Option 4: $\frac{1}{2}(x+y+z)$

Team Careers360 25th Jan, 2024

Correct Answer: $\frac{1}{2}(x+y+z)$


Solution : By polynomial identity
$x^3+y^3+z^3−3xyz = (x+y+z)(x^2+y^2+z^2−xy−yz−zx)$ 
= $\frac{1}{2}(x+y+z)(2x^2+2y^2+2z^2−2xy−2yz−2zx)$
= $\frac{1}{2}(x+y+z)(x^2−2xy+y^2+y^2−2yz+z^2+z^2−2xz+x^2)$
= $\frac{1}{2}[(x+y+z)(x−y)^2+(y−z)^2+(z−x)^2]$
$\therefore \frac{x^3+y^3+z^3-3 x y z}{(x-y)^2+(y-z)^2+(z-x)^2}$ = $\frac{\frac{1}{2}[(x+y+z)(x−y)^2+(y−z)^2+(z−x)^2]}{(x-y)^2+(y-z)^2+(z-x)^2}$ = $\frac{1}{2}(x+y+z)$
Hence, the correct answer is $\frac{1}{2}(x+y+z)$.
