When two odd numbers are added together, the result is always an even number. This is because odd numbers can be represented as 2n+1, where n is any integer. When two odd numbers are added, the 2n terms cancel each other out, leaving only 2 remaining, which is an even number. Therefore, the sum of two odd numbers is always an even number.

To find the missing number that, when added to 3 tens (30), equals 33, we can subtract 30 from 33 to get the missing number. Therefore, the missing number is 3.

The number 356 is an even number because it is divisible by 2 without leaving a remainder. Even numbers are those that can be divided by 2, while odd numbers cannot be divided by 2 without leaving a remainder.

To find the missing number, we need to subtract 5 tens from 51. This will give us the value of the missing number. 51 - 50 = 1. Therefore, the missing number is 1.

The odd number just before 51 is 49 because odd numbers are integers that are not divisible by 2. Since 51 is an odd number, the odd number just before it would be the previous odd number, which is 49.

One year is equal to 12 months, and 5 months is an additional 5 months. Therefore, one year and 5 months equals a total of 17 months.

The given equation states that ".......... km" is equal to "4000 m". This means that the value of ".......... km" is equal to 4000 m. Among the options provided, option 4 is the only one that represents the value of 4000. Therefore, option 4 is the correct answer.

To convert grams to kilograms, we divide the number of grams by 1000. In this case, 2000 grams divided by 1000 equals 2 kilograms.

The pattern in the given sequence is that each number is double the previous number. Starting with 6, the next number is obtained by multiplying 6 by 2, which gives 12. Similarly, 12 is multiplied by 2 to get 24. Following this pattern, the next number would be 24 multiplied by 2, which equals 48. Therefore, the missing number in the sequence is 48.

The probability of an impossible event is always 0. This is because an impossible event cannot occur under any circumstances, so the likelihood of it happening is zero.

To convert hours to minutes, we multiply the number of hours by 60 since there are 60 minutes in 1 hour. Therefore, 2 hours multiplied by 60 equals 120 minutes.

The number 1 is the smallest odd number because it is the only odd number that is less than 2. Odd numbers are integers that cannot be divided evenly by 2, and 1 is the only number that meets this criteria and is smaller than any other odd number.

The day consists of 24 hours.

The perimeter of a square is calculated by multiplying the length of one side by 4. In this case, the side length of the square is given as 5 cm. Therefore, the perimeter of the square would be 5 cm x 4 = 20 cm.

The perimeter of an equilateral triangle is found by multiplying the length of one side by 3. In this case, the side length is 4 cm, so the perimeter would be 4 cm x 3 = 12 cm.

There are 7 days in a week, so to find the number of days in 5 weeks, we can multiply 7 by 5. This gives us 35 days.

To find the product of 136 and 100, we need to multiply 136 by 100. When we multiply any number by 100, we move the decimal point two places to the right. So, multiplying 136 by 100 gives us 13600. Therefore, the correct answer is 13600.

The probability of a certain event occurring is always 1. This means that the event is guaranteed to happen and there is no possibility of it not occurring.

To find the number that, when multiplied by 5, results in 255, we can set up the equation 5x = 255, where x represents the unknown number. Dividing both sides of the equation by 5, we get x = 51. Therefore, the correct answer is 51.

The perimeter of a triangle is the sum of the lengths of its sides. In this case, the triangle has side lengths of 5 cm, 5 cm, and 7 cm. Therefore, the perimeter of the triangle is 5 cm + 5 cm + 7 cm = 17 cm.

The given question asks for the conversion of 6 kg and 250 gm into grams. To convert kilograms to grams, we multiply the value by 1000. Therefore, 6 kg is equal to 6000 gm. Adding the additional 250 gm, the total comes out to be 6250 gm.

The normal body temperature is 37 degrees Celsius. This is the average temperature at which the human body functions optimally. It is considered to be the baseline temperature for most healthy individuals. Deviations from this temperature can indicate illness or other health conditions.

The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, the length is given as 5 cm and the width as 3 cm. Therefore, the perimeter would be 2 times the length plus 2 times the width, which is (2 * 5) + (2 * 3) = 10 + 6 = 16 cm.

The smallest even number is 0 because it is the only even number that is divisible by 2 and has no remainder. Any other even number would be greater than 0, such as 2, 4, 6, etc. Therefore, 0 is the correct answer as it is the smallest even number.

The given question asks for the conversion of 66 meters to centimeters. Since there are 100 centimeters in one meter, we can multiply 66 by 100 to get the equivalent in centimeters. Therefore, 66 meters is equal to 6600 centimeters.

If we divide a number by 5 and the result is 5, then the original number must be 25.

One year consists of 12 months, and a quarter year consists of 3 months. Therefore, when we add one year and a quarter year together, we get a total of 12 + 3 = 15 months.

Two days consist of 48 hours, and two hours are added to that, resulting in a total of 50 hours.

When tossing a coin once, it is possible to get a tail. This is because a coin has two sides, heads and tails, and when it is tossed, there is a 50% chance of it landing on either side. Therefore, the event of getting a tail when tossing a coin once is possible.
