Correct Answer: 5

Solution :
Given: AD = 9 cm
BE = 6 cm
$\angle$DGB = 90°
Here, the point of intersection of its medians, G divides the median in the ratio 2:1.
So, DG = $\frac{1}{3}×$AD = $\frac{1}{3}×9=3$ cm
BG = $\frac{2}{3}×$BE = $\frac{2}{3}×6=4$ cm
From Pythagoras theorem we

= 155%
Hence, the correct answer is 155%.

Correct Answer: 24 cm

Solution :
Given, Radius = 13 cm
CD = 8 cm
⇒ OC = 13 – 8 = 5 cm [As OD is the radius]
In $\triangle AOC$,
Using Pythagoras theorem, we get,
$AO^2=OC^2+AC^2$
⇒ $13^2=5^2+AC^2$
⇒ $AC^2=169-25$
⇒ $AC=\sqrt{144}$
$\therefore AC = 12$ cm
Now,

Correct Answer: 16.66%

Solution : As per the given graph,
The number of boys using Facebook in January = 600
The number of boys using Facebook in February = 500
The percentage decreases $=\frac{600-500}{500}×100=16.66\%$
Hence, the correct answer is 16.66%.
