BITSAT Logical Reasoning Test - JEE MCQ

1,2,5 are figures that have patterns formed from four lines curved in a concave direction.
3,7,8 are figures that have patterns formed from four lines curved in a convex direction.
4,6,9 are figures that have patterns formed from these straight lines.

The currency of Thailand is the Baht.

Explanation:

- Identifying the pattern:
- Looking at the given letter series, we can see that the letters are alternating between "g", "i", "f", and "e" in a specific order.

- Completing the series:
- By following the pattern, we can determine that the missing letters should be "i", "f", "g", "i", and "e".

- Choosing the correct option:
- Comparing the missing letters with the options provided, we can see that option C: ifgie matches the pattern and completes the series correctly.

Therefore, the correct answer is C: ifgie.

The given sequence is a combination of two series:
I. 3, 8, 13, 18, 23 and

II. 2, 9, 22, 32, 42

The pattern in I is + 5, and the pattern in II is + 10.

So, in II, 9 is wrong and must be replaced by (2 + 10) i.e. 12.

To determine the correct mirror image of the figure (X) from the given alternatives, let's analyze the original figure and its mirror image characteristics:

1. Original Figure (X):
   - The figure is a square containing a "Z" shape with a line and an arrow at the bottom pointing right.

2. Mirror Image Characteristics:
   - A mirror image will reverse left and right but maintain top and bottom orientation.
   - The "Z" shape will be inverted horizontally.
   - The line and arrow at the bottom will have the arrow pointing left instead of right.

3. Options Analysis:
   - Option A: The arrow at the bottom is pointing right, which is incorrect.
   - Option B: The arrow at the bottom is pointing left, and the "Z" is correctly mirrored.
   - Option C: The arrow at the bottom is pointing right, which is incorrect.
   - Option D: The arrow at the bottom is pointing left, but the "Z" is not correctly mirrored.

Therefore, the correct mirror image of figure (X) is option B.

Options Analysis:
   - Option A: The 'Y' shape is not inverted correctly.
   - Option B: The 'Y' shape and the sign are not in the correct positions.
   - Option C: The 'Y' shape is pointing in the same direction as the original, not mirrored.

- Option D: The 'Y' shape is correctly inverted vertically, and the sign is at the top. 

Therefore, the correct mirror image of figure (X) is Option D.

Answer: (c) EFMIJ

Explanation: Each letter in the word NOIDA is moving one step forward and forms the code OPJEB. Similarly, if the letters of the word DELHI moves one step forward, then D will be written as E, E as F, L as M, H as I, and I as J. So, the code for DELHI will be EFMIJ.
