Question : If the sum of all interior angles of a regular polygon is 14 right angles, then its number of sides is:
Option 1: 8
Option 2: 9
Option 3: 7
Option 4: 6
Correct Answer: 9
Solution : Sum of all interior angles = $14×90^{\circ}$ = $1260^{\circ}$ Let the number of sides of the polygon be $n$. ⇒ $1260^{\circ}$ = $(n-2)×180^{\circ}$ ⇒ $(n-2)$ = $\frac{1260}{180}$ ⇒ $(n-2)$ = $7$ ⇒ $n$ = $2+7$ = $9$ Hence, the correct answer is 9.
Question : If $\cos \theta-\sin \theta=\sqrt{2} \sin \theta$, then $(\cos \theta+\sin \theta)$ is:
Option 1: $-\sqrt{2} \cos \theta$
Option 2: $\sqrt{2} \cos \theta$
Option 3: $\sqrt{2} \tan \theta$
Option 4: $-\sqrt{2} \sin \theta$
Correct Answer: $\sqrt{2} \cos \theta$
Solution : According to the question, ⇒ $\cos \theta-\sin \theta=\sqrt{2} \sin \theta$ ⇒ $(\cos\theta + \sin\theta)^{2} = 2 \sin^{2}\theta$ ⇒ $\cos^{2}\theta + \sin^{2}\theta + 2\sin\theta\cos~\theta = 2\sin^{2}\theta$ ⇒ $\sin^{2}\theta - \cos^{2}\theta - 2\sin~\theta~cos\theta = 0$ ⇒ $\sin^{2}\theta + \cos^{2}\theta - 2\sin\theta\cos\theta = 2 \cos^{2}\theta$ ⇒
Question : Let $x$ be the least number of 4 digits that when divided by 2, 3, 4, 5, 6 and 7 leaves a remainder of 1 in each case. If $x$ lies between 2000 and 2500, then what is the sum of the digits of $x$?
Option 1: 4
Option 2: 15
Option 3: 9
Option 4: 10
Correct Answer: 4
Solution :
LCM of 2, 3, 4, 5, 6 and 7 is 420. The number should be between 2000 and 2500. So, the number is = 420 × 5 = 2100 The remainder will be 1 in each case so the number = 2100 + 1 =
