Explanation

Each of the numbers except 14 is an odd number.

The number '14' is the only EVEN number

Explanation

HCF Stand for Highest Common factor

The HCF of 26 and 91 is 13.

Factor of 26

26 = 1 x 2 x 13

Factor of 91

91 = 1x 7 x 13

So highest is 13

Explanation

Explanation

Step 1:
Take half of the first number.

Step 2:
Take half of the second number.

Step 3:
Concatenate the two halves (treating them as digits).

Let's verify with the given examples:

• 6 × 2:
  Half of 6 is 3 and half of 2 is 1. Concatenating these gives 31.

• 8 × 4:
  Half of 8 is 4 and half of 4 is 2. Concatenating these gives 42.

• 2 × 2:
  Half of 2 is 1 and half of 2 is 1. Concatenating these gives 11.

• 6 × 6:
  Half of 6 is 3 and half of 6 is 3. Concatenating these gives 33.

Now, apply the same logic to 8 × 6:

• Half of 8 is 4.

• Half of 6 is 3.

When you concatenate 4 and 3, you get 43.

Thus, the answer to 8 × 6 = 43.

Explanation

Let third number = x

First number = 120/100 x = 6x/5

Second number = 150/ 100x = 3x/2

Ratio of two numbers = 6x/5 : 3x/2 = 12x : 15x = 4:5

Explanation

The sum of five numbers is 555.

The average of the first two numbers is 75, so their sum is 2 x 75 = 150.

The third number is 115.

So, the sum of the first three numbers is 150 + 115 = 265.

Since the sum of all five numbers is 555, the sum of the last two numbers is 555 - 265 = 290.

Therefore, the average of the last two numbers is 290 / 2 = 145.

The correct answer is: 145

Explanation

A circle does not have a side and hence no vertex.

Hence, "circle" is different from all other given shapes.

 the square has 4 sides,

A hexagon has 6 sides,

triangle has 3 sides. 

Explanation

To find the number of good apples, you can subtract the number of bad apples from the total number of apples.

First, calculate the number of bad apples:

2/9 of 27 = (2/9) × 27 = 6

So, there are 6 bad apples.

To find the number of good apples, subtract the bad apples from the total:

27 - 6 = 21

Therefore, there are 21 good apples.
