Question : Which of the following relations is correct for $0< \theta < 90^{\circ}$?
Option 1: $\sin \theta = \sin^{2}\theta$
Option 2: $\sin \theta < \sin^{2} \theta$
Option 3: $\sin \theta > \sin^{2}\theta$
Option 4: $\sin \theta > \operatorname{cosec}^{2}\theta$
Correct Answer: $\sin \theta > \sin^{2}\theta$
Solution : For $(0 < \theta < 90^{\circ})$, the correct relation is: $\sin\theta > \sin^{2}\theta$ Here's why: ⇒ \(\sin^{2}\theta\) is the square of \(\sin\theta\) and since \(\sin\theta\) is less than 1 for \(0 < \theta < 90^0\), \(\sin^{2}\theta\) will be less than \(\sin\theta\). ⇒
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.) (15, 23, 31) (33, 41, 49)
Option 1: (21, 29, 43)
Option 2: (20, 28, 36)
Option 3: (20, 33, 28)
Option 4: (35, 43, 56)
Correct Answer: (20, 28, 36)
Solution : Given: (15, 23, 31); (33, 41, 49)
The pattern is as follows – (15, 23, 31)→15 + 31 = 46; 2 × 23 = 46 (33, 41, 49)→49 + 33 = 82; 2 × 41 = 82 Let's check the options – First

Solution : Given: (11, 13, 143), (17, 11, 187)
Here, (11, 13, 143)→11 × 13 = 143 (17, 11, 187)→17 × 11 = 187
Let's check the given options – First option: (3, 4, 7)→3 × 4 = 12 ≠ 7 Second option: (3, 4,
Question : The circumference of a circle is equal to the perimeter of an equilateral triangle. If the radius of the circle is 7 cm, what is the length of the side of the equilateral triangle?
Option 1: $\frac{22}{3}$ cm
Option 2: $\frac{44}{3}$ cm
Option 3: $44$ cm
Option 4: $22$ cm
Correct Answer: $\frac{44}{3}$ cm
Solution : The radius of the circle ($r$) = 7 cm Let 'a' be the side of an equilateral triangle. The circumference of a circle is equal to the perimeter of an equilateral triangle. $2 \pi r$ = 3a ⇒ a = $\frac{2 \pi r}{3}$ =
