Correct Answer: 31 litres

Solution : To determine the maximum capacity, we need to find the HCF of 403, 434 and 465.
The prime factors of 403, 434 and 465 are:
⇒ 403 = 13 × 31
⇒ 434 = 2 × 7 × 31
⇒ 465 = 3 ×

Correct Answer: Gamma ray

Solution : The correct answer is Gamma ray.

Radioactive nuclei emit three types of radiation: alpha, beta, and gamma rays. Alpha rays have the highest ionising power but the least penetrating power. Gamma rays are photons emitted by radioactive nuclei and have the lowest ionising power,

Correct Answer: 26

Solution : Given:
7: 40:: ?: 667:: 39: 1512

Subtract 9 from the square of the first term to get the second number –
Like in, 7 : 40→7² – 9 = 40
And in, 39 : 1512→39² – 9 = 1512
Similarly, follow the

Correct Answer: 14

Solution : Given:
$m^n=169$
⇒ $m^n=13^2$
So, $m=13, n=2$
Now, $(m+1)^{n-1}$
= $(13+1)^{2-1}$
= $(14)^{1}$
= $14$
Hence, the correct answer is 14.

Correct Answer: 72.8

Solution : Let the base radius and height of the cone be r and h respectively 
Then, volume = $\frac{1}{3}\pi r^2h=V$
If base radius is increased 20 %, new radius = $r\times \frac{120}{100}=\frac{6}{5}r$
Similarly, New height = $\frac{6}{5}h$
New volume = $\frac{1}{3}(\frac{6}{5}r)^2\times \frac{6}{5}h=\frac{216}{125} V$
Hence, percentage increase
