Correct Answer: 1 : 8

Solution : The curved surface area of a cone $ = \pi rl$ where \(r\) is the radius and \(l\) is the slant height of the cone.
Given that the ratio of the curved surface areas of two cones = 1 : 4
$⇒\frac{\pi r_1

Correct Answer: 10

Solution : Given: The value of the trigonometric equation is $\tanθ + \cotθ = 2$ where $θ$ is an acute angle.
$\tanθ + \cotθ = 2$
⇒ $\tan 45^{\circ} + \cot45^{\circ} = 2$
⇒ $\theta = 45^{\circ}$
The value of the trigonometric expression $2 \tan^{25}45^{\circ} + 3

Correct Answer: 62208

Solution : Given:
2, 12, 144, 2592, ?

The pattern is as follows –

So, 62208 is the missing number of the series. Hence, the second option is correct.

Correct Answer: (49, 64, 81)

Solution : Given:
(4, 9, 16); (25, 36, 49)

The given numbers are squares of consecutive natural numbers –
⇒ (4, 9, 16)→2² = 4; (2 + 1)² = 3² = 9; (3 + 1)² = 4² = 16
⇒

Correct Answer: JCTRSS

Solution : Given:
SETTLE is coded as DLSTDS.

Subtract 1 from the place value of the second, fourth, and sixth letters of SETTLE and the remaining letters will remain the same and then reverse the order of the letters as shown to obtain the code –

Thus,

Correct Answer: Muscular force

Solution : The correct answer is Muscular force.

Contact force is the force generated when two things come into contact with each other. Here, non-contact forces such as gravitational, magnetic, and electrostatic can act at a distance without making physical contact with the object. On
