Question : If the surface area of a sphere is 346.5 cm2, then its radius is: (Take $\pi=\frac{22}{7}$)

Option 1: 7 cm

Option 3: 5.25 cm

Option 4: 9 cm

Team Careers360 24th Jan, 2024

Correct Answer: 5.25 cm


Solution : Given: Surface area of a sphere = 346.5 cm2
Let the radius of the sphere be $r$.
We know, the surface area of a sphere $= 4\pi r^2$
⇒ $346.5 = 4\pi r^2$
⇒ $r^2$ = $\frac{346.5×7}{4×22}$
⇒ $r^2= 27.5625$
$\therefore r =

Question : If $\alpha$ and $\beta$ are the roots of equation $x^{2}-2x+4=0$, then what is the equation whose roots are $\frac{\alpha ^{3}}{\beta ^{2}}$ and $\frac{\beta ^{3}}{\alpha ^{2}}?$

Option 1: $x^{2}-4x+8=0$

Option 2: $x^{2}-32x+4=0$

Option 3: $x^{2}-2x+4=0$

Option 4: $x^{2}-16x+4=0$

Team Careers360 22nd Jan, 2024

Correct Answer: $x^{2}-2x+4=0$


Solution : Given: $\alpha$ and $\beta$ are roots of the equation $x^{2}-2x+4=0$
⇒ $\alpha+\beta=2$ and $\alpha\beta=4$
Now we need to find the equation whose roots are $\frac{\alpha ^{3}}{\beta ^{2}}$ and $\frac{\beta ^{3}}{\alpha ^{2}}$.
$\frac{\alpha^{3}}{\beta^{2}}+\frac{\beta^{3}}{\alpha^{2}}$
= $\frac{\alpha ^{5}+\beta^{5}}{\alpha^{2}\beta ^{2}}$
= $\frac{(\alpha ^{2}+\beta^{2}) \times(\alpha ^{3}+\beta^{3})-(\alpha ^{2}\beta ^{3}+\alpha ^{3}\beta ^{2})}{(\alpha\beta)^{2}}$

Question : If the HCF of two numbers is 8, then which of the following can never be their LCM?

Option 1: 56

Option 2: 48

Option 3: 42

Option 4: 40

Team Careers360 20th Jan, 2024

Correct Answer: 42


Solution : Since the HCF of two numbers is 8,
LCM of the two numbers will only be a multiple of 8.
So, the LCM can be 56, 48, and 40 but never be 42.
Hence, the correct answer is 42.
