Odd one out maths picture quiz And Answer

Option C

In shape A, the outer figure possesses 4 sides, while the inner figure contains 3 sides.
In shape B, the outer figure exhibits 5 sides, while the inner figure showcases 4 sides.
In shape C, both the outer figure and the inner figure encompass 4 sides.
In shape D, the outer figure displays 7 sides, and the inner figure encompasses 6 sides.

Apart from Shape C, in all the other shapes, the number of sides on the outer figure exceeds that of the inner figure by just one.

All other shapes are quadrilaterals, while a hexagon has six sides.

Rotating Shape A by 90 degrees counterclockwise aligns it with Shape B.

Rotating Shape A by 90 degrees clockwise aligns it with Shape C.

This establishes that A equals B equals C, making D the exception.

Among the given numbers: 7984, 2450, 5964, 1928, 4779, 6884, 0326

The pattern is based on the product of the second and third digits, compared to the combination of the first and last digits.

Following this pattern:

7984: Product of second and third digits = 9 * 8 = 72, which doesn't match the combination of the first and last digits (74).
2450: Product of second and third digits = 4 * 5 = 20, which matches the combination of the first and last digits (20).
5964: Product of second and third digits = 9 * 6 = 54, which matches the combination of the first and last digits (54).
1928: Product of second and third digits = 9 * 2 = 18, which matches the combination of the first and last digits (18).
4779: Product of second and third digits = 7 * 7 = 49, which matches the combination of the first and last digits (49).
6884: Product of second and third digits = 8 * 8 = 64, which matches the combination of the first and last digits (64).
0326: Product of second and third digits = 3 * 2 = 6, which matches the combination of the first and last digits (06).

Based on this accurate pattern breakdown, the odd one out is "7984."

Third Image

Explanation
It's the only image that is not symmetric around the vertical axis as illustrated in the picture below.

Upon careful observation, the following becomes evident:

Shape A features an inner figure(dark black) in the form of a trapezoid.

Conversely, shapes B, C, and D all exhibit an inner figure shaped as a triangle.

As a result, the image that deviates from this pattern is Shape A, making it the odd one out.

Let us add the digits:
2 + 7 + 1 + 6 = 16
4 + 1 + 3 + 5 = 13
5 + 3 + 2 + 1 = 11
7 + 1 + 4 + 5 = 17

As you can see, only 2716 is a number whose digits add up to be a non prime number. Thus it is the odd one out.

3rd.

In all the structure, we can find 2 rectangles are found except one i.e 3rd.

9862

Sum of digits of all other numbers is 21 , but sum of digits of 9862 is 25

The odd number is 820670987.

If you add up the first three digits of all the numbers, it adds up to 14 except for the third option i.e. 820670987.
