Runs scored by Pujara is what % of runs scored by all these 5 players? 

Option 1: 25%

Option 2: 30%

Option 3: 20%

Question : If $x+y+z=13,x^2+y^2+z^2=133$ and $x^3+y^3+z^3=847$, then the value of $\sqrt[3]{x y z}$ is:

Option 1: $8$

Option 2: $7$

Option 3: $-9$

Option 4: $-6$

Team Careers360 9th Jan, 2024

Correct Answer: $-6$


Solution : Given: $x+y+z=13,x^2+y^2+z^2=133$
and $x^3+y^3+z^3=847$
$(x+y+z)^2 = x^2+y^2+z^2+2(xy+yz+zx)$
⇒ $13^2=133+2(xy+yz+zx)$
⇒ $xy+yz+zx=\frac{169-133}{2}=\frac{36}{2}=18$
$x^3+y^3+z^3-3xyz = (x+y+z)(x^2+y^2+z^2-(xy+yz+zx))$
$⇒847-3xyz = 13 ×(133-18)$
$⇒-3xyz = 13×115 - 847 = 1495-847 =648 $
$⇒xyz = \frac{648}{-3} = -216$
$\therefore \sqrt[3]{xyz} = \sqrt[3]{-216} = -6$
Hence, the correct answer is $-6$.

Question : If each side of a square is decreased by 17%, then by what percentage does its area decrease?

Option 1: 25%

Option 2: 30.79%

Option 3: 31.11%

Option 4: 44.31%

Team Careers360 10th Jan, 2024

Correct Answer: 31.11%


Solution : Let the side of the square be 100.
After decrement of 17% = 83
Initial area = $(side)^2$
= $100^2$
= 10000
Area after decrement = $83^2$
= 6889
Difference in areas = 10000 – 6889 = 3111
Decrease in area (in percentage) = $\frac{\text{Decrease
