All questions of Fun with Numbers (Numbers 21 to 99) for Class 1 Exam

The result of 6 multiplied by 9 is 54.

Explanation:
To find the product of two numbers, we multiply them together. In this case, we want to find the product of 6 and 9.

We can start by setting up the multiplication problem like this:

6
x 9
------
To solve this multiplication problem, we multiply each digit of the first number (6) by each digit of the second number (9).

Multiplying the ones place:
6 multiplied by 9 equals 54.

So, the product of 6 multiplied by 9 is 54.

Therefore, the correct answer is option 'A' which is 54.

8 tens are equal to 80, and 4 ones are 4. When you subtract 1 from 80 + 4, you get 79 + 4, which is 83.

Explanation:

The smallest number is determined by looking at the ones place value in each option.

- a) 2 tens: This represents the number 20, with 0 ones.
- b) 2 tens 5 ones: This represents the number 25, with 5 ones.
- c) 2 tens 7 ones: This represents the number 27, with 7 ones.

Since 0 is smaller than both 5 and 7, the smallest number among the options is 2 tens (20) in option A.

Therefore, the smallest number is option A) 2 tens.

Before 39:
To determine which number comes before 39, we need to look at the numbers that are smaller than 39 in the given options.

Options:
a) 40
b) 39
c) 38
d) 29

Analysis:
When we compare the numbers in the options to 39, we find that 38 is the number that comes before 39 in the given list. Therefore, the answer is option 'c) 38'.

Conclusion:
The number that comes before 39 is 38, which is option 'c'.

Understanding Mathematical Symbols
In mathematics, symbols are used to represent relationships between numbers and values. One of these symbols is the "less than" sign.
What Does "Less Than" Mean?
- The "less than" sign is represented by the symbol < />
- It indicates that one number is smaller than another.
- For example, if we say 3 < 5,="" it="" means="" that="" 3="" is="" less="" than="" />
Identifying the Correct Option
Among the options provided:
- a) / does not represent a mathematical relationship.
- b) > is the "greater than" sign, indicating that one number is larger than another.
- c) < is="" the="" "less="" than"="" sign,="" which="" is="" what="" we="" are="" looking="" />
- d) = signifies equality, meaning both sides are the same.
Thus, the correct answer is option 'C'.
Why is This Important?
- Understanding these symbols is crucial for solving mathematical problems.
- It helps in comparing numbers and understanding inequalities.
- Mastering these basics is foundational for further studies in mathematics.
In summary, the "less than" sign (<) allows="" us="" to="" make="" comparisons="" between="" numbers,="" making="" it="" an="" essential="" concept="" in="" mathematics.="" allows="" us="" to="" make="" comparisons="" between="" numbers,="" making="" it="" an="" essential="" concept="" in="">

The series is incrementing by 1 in each step. Starting from 69, the next number is 69 + 1, which equals 70.

The number that comes between 39 and 41 is 40.

9 tens are equal to 90, and 6 ones are 6. When you combine them, you get 90 + 6, which is 96.

Equals to (=) sign is used to show that two numbers are equal to each other, like 2 = 2.

Option C is incorrect because 10 - 1 is not equal to 10. The correct answer is 10 - 1 = 9.

The series is decreasing by 1 in each step. Starting from 21, the next number is 21 - 1, which equals 20.

The pattern in the series is that all numbers are multiples of 10 except 75, which is not a multiple of 10. Therefore, 75 is the odd one out.

The given series is increasing by Rs.1 in each step. So, to complete the series, the next number is Rs.14 + 1 = Rs.15.

The series in option C is not in order as it jumps from 77 to 79, breaking the pattern of incrementing by 1.

The correct number name for 53 is "Fifty three."

7 tens are equal to 70, and 2 ones are 2. When you combine them, you get 70 + 2, which is 72.

The given series is an increment of 2 in each step. Starting from 50, each number is increased by 2. So, the missing number is 54 + 2 = 56.

You can put 6 more eggs in the basket to fill it to its capacity of 10.

In the given series, all numbers are consecutive except for 17, which breaks the pattern. Therefore, 17 is the odd one out.

The series is increasing by Rs.100 in each step. Starting from Rs.500, the next number is Rs.500 + Rs.100, which equals Rs.600.
