Question : A concave lens forms an image which is:
Option 1: real and erect
Option 2: virtual and erect
Option 3: real and inverted
Option 4: virtual and inverted
Correct Answer: virtual and erect
Solution : The correct option is virtual and erect.
A concave lens produces a virtual, upright, and diminished image. This is because the rays of light diverge after passing through the lens. When extended backwards, these divergent rays seem to meet at a point

Question : Simplify. $\frac{\sin8\theta \cos\theta - \sin6\theta \cos3\theta}{\cos2\theta \cos\theta - \sin3\theta \sin4\theta}$
Option 1: $\cot \theta$
Option 2: $\cot 2 \theta$
Option 3: $\tan \theta$
Option 4: $\tan 2 \theta$
Correct Answer: $\tan 2 \theta$
Solution : Given: $\frac{\sin8\theta \cos\theta - \sin6\theta \cos3\theta}{\cos2\theta \cos\theta - \sin3\theta \sin4\theta}$ = $\frac{2\sin8\theta \cos\theta - 2\sin6\theta \cos3\theta}{2\cos2\theta \cos\theta - 2\sin3\theta \sin4\theta}$ = $\frac{\sin(8\theta+\theta)+\sin(8\theta-\theta)-\sin(6\theta+3\theta)-\sin(6\theta-3\theta)}{\cos(2\theta+\theta)+\cos(2\theta-\theta)-\cos(3\theta-4\theta)+\cos(3\theta+4\theta)}$ = $\frac{\sin9\theta + \sin7\theta - \sin9\theta - \sin3\theta}{\cos3\theta + \cos\theta - \cos(-\theta)+cos7\theta}$ = $\frac{\sin7\theta-\sin3\theta}{\cos3\theta + \cos\theta - \cos\theta+cos7\theta}$ = $\frac{\sin7\theta-\sin3\theta}{\cos7\theta+cos3\theta}$ =
Question : Directions: Given below are two statements and two conclusions.

Option 4: 3, 2, 5, 4, 1
Correct Answer: 4, 3, 2, 5, 1
Solution : Given: 1. Brochure 2. Brine 3. Bright 4. Brief 5. Brocade
Step 1: Compare the first and second letters of each word. Since all the words start with the same letter B and are followed by r, then move on
Question : Directions: In a certain code language, FLORA is written as WQOLC, and MONEY is written as PNPYE. How will GOING be written in that language?
Option 1: VNUPW
Option 2: RMWEH
Option 3: VBUDP
Option 4: RHKSR
Correct Answer: VNUPW
Solution : Given: FLORA is written as WQOLC and MONEY is written as PNPYE.
Add 2 in the first two letters and add 3 in the next three letters of opposite letters of FLORA to obtain the required code – F → U + 2 = W,
