First five positive numbers = 2, 3, 5, 7 and 11

Hence, Option D is correct.

x% of y% of 125 = 5% of 900

x × y = 3600
Hence, Option D is correct.

First, second, fourth term are in proportion. The third term will also be in proportion.

First : Second::Third : Fourth

First term =16

Second term =24

Fourth term =54

Third term = x

x = 2 × 18

x = 36

10 men = 20 women
Man : Woman = 2 : 1

Hence, Option B is correct.

8 × 39 + 13 × 43 = 871
Since the 8th number came twice, it is added two times.
So the answer = 871 – 20 × 41 = 51
Hence, Option A is correct.

(The volume of cube = side³)
The ratio of sides = ∛8 : ∛27 = 2 : 3
Hence, Option B is correct.

Alcohol = 40% of 120 = 48

Hence, Option C is correct.

The given series consists of consecutive prime numbers starting from 17. The next prime number after 29 is 31.

Thus, the missing number is 31.

According to question,
A's weight is twice as much as of B.
1. A = 2B.
B's weight is four and half times as much as of C.
2. B = 4.5C
C's weight is half times as much as of D.
3. C = D/2.
D's weight is half as much as of E.
4. D = E/2.
E weight is less than A but more than C.
5. A > E > C
from 1 and 2
6. A = 2B = 9C
from 6 and 3
7. A = 2B = 9C = 4.5D
from 7 and 4
8. A = 2B = 9C = 4.5D = 2.25E
so from 8 and 5
A > B > E > D > C
Descending order of weights of the articles will be
A, B, E, D, C

in the figure the 8 triangle is shown easily and another is COD , DOB, BOA, AOC, ACD, BDC,ABC, ABD so that total no. of triangle is 8 + 8 = 16

The answer is B: Eagle.

Explanation:
Kiwi, Emu, and Ostrich:
- These are all flightless birds.
- They belong to a group of birds called ratites, which have flat breastbones without a keel.
- They are generally large, ground-dwelling birds that rely on running for defense and movement.
Eagle:
- Eagles are powerful birds of prey.
- They have strong wings and are capable of flight.
- They belong to the family Accipitridae, which includes hawks, kites, and harriers.
Conclusion: The word that is different from the rest is B: Eagle, because it is a bird of prey capable of flight, while the others are flightless birds.

As, 68 = (4)³ + 4

    130 = (5)³ + 5

and 350 = (7)³ + 7

Therefore, ? = (6)³ + 6 = 222

Clearly, the order of letters in the word is reversed and then each letters is replaced by the numeral denoting its position in the English alphabet. Next, 2 is added to each numeral and the numerals so obtained are joined together physically to get the code. Thus, we have :

RED → DER → 4/5/18 → 6/7/20 → 6720.

GREEN → NEERG → 14/5/5/18/7 → 16/7/7/20/9 → 1677209.
Hence, option B is correct.

Resolution refers to the pixel spacing or the level of detail that can be displayed or captured by a digital device. It is an important factor in determining the clarity and sharpness of images.

Here are some key points to understand about resolution:

• Resolution is measured in pixels per inch (PPI) or dots per inch (DPI). It indicates the number of pixels or dots that can be displayed in one inch of a digital image.


• Higher resolution means more pixels or dots per inch, resulting in greater detail and sharper images.


• Lower resolution means fewer pixels or dots per inch, resulting in less detail and more pixelation.


• Resolution is a crucial factor in various digital devices, such as computer monitors, cameras, printers, and smartphones.


• For example, a higher resolution in a camera allows for capturing more details in an image, while a higher resolution in a monitor provides a clearer and more detailed display.


• Resolution is often expressed as the width and height of an image in pixels, such as 1920x1080 for Full HD or 3840x2160 for 4K Ultra HD.

Therefore, in the context of pixel spacing, the correct answer is B: Resolution.
