Amit Khanna answered |
210 + 101 – 10 = 301
120 + 110 – 15 = 215
Thus, 301 > 215
120 + 110 – 15 = 215
Thus, 301 > 215

Devika Deshpande answered |
Calculation of the difference between two digit largest and two digit smallest number:
- Two-digit largest number: 98
- Two-digit smallest number: 10
Steps:
1. Subtract the two-digit smallest number from the two-digit largest number:
98 - 10 = 88
2. Therefore, the difference between the two-digit largest number (98) and the two-digit smallest number (10) is 88.
Explanation:
The largest two-digit number is 98 (9 tens and 8 ones), and the smallest two-digit number is 10 (1 ten and 0 ones). When we subtract 10 from 98, we get 88. This means that the difference between the largest and smallest two-digit numbers is 88. Therefore, the correct answer is option 'D' which states 89.
- Two-digit largest number: 98
- Two-digit smallest number: 10
Steps:
1. Subtract the two-digit smallest number from the two-digit largest number:
98 - 10 = 88
2. Therefore, the difference between the two-digit largest number (98) and the two-digit smallest number (10) is 88.
Explanation:
The largest two-digit number is 98 (9 tens and 8 ones), and the smallest two-digit number is 10 (1 ten and 0 ones). When we subtract 10 from 98, we get 88. This means that the difference between the largest and smallest two-digit numbers is 88. Therefore, the correct answer is option 'D' which states 89.

- Step 2: Now, add the total from Step 1 to the number of black balls:
- 15 (from Step 1) + 6 (black) = 21
Final Count
Thus, Aviral has a total of 21 balls in total.

Understanding the Equation
To solve the equation 22 + 9 = 11 + ____, we need to find the missing number that makes both sides equal.
Breaking Down the Left Side
- Calculate the left side:
- 22 + 9 = 31
Breaking Down the Right Side
- We currently have:
- 11 + ____
- Let’s denote the missing number as 'x':
- So, we rewrite the right side as:
- 11 + x
Setting Both Sides Equal
- Now we equate both sides:
- 31 = 11 + x
Finding the Missing Number
- To find 'x', we can rearrange the equation:
- x = 31 - 11
- x = 20
Conclusion
- The missing number is 20, which corresponds to option 'A'.
By confirming our calculations, we see that if we replace the blank with 20, both sides of the equation will equal 31, thereby validating that the answer is indeed correct.
This exercise reinforces basic addition and the concept of balancing equations, which are fundamental skills in mathematics for young learners.

Understanding the Problem
To solve the problem, we first need to evaluate the expressions provided:
- Calculate 7 + 5 and 8 + 6:
- 7 + 5 = 12
- 8 + 6 = 14
So, we are looking for numbers that are greater than 12 but less than 14.
Evaluating the Options
Now, let's evaluate each of the provided options:
- Option a: 10 + 3
- 10 + 3 = 13
- 13 is greater than 12 and less than 14.
- Option b: 7 + 6
- 7 + 6 = 13
- 13 is also greater than 12 and less than 14.
- Option c: 8 + 5
- 8 + 5 = 13
- 13 is again greater than 12 and less than 14.
Conclusion
Since all three options (a, b, and c) yield a result of 13, which meets the criteria of being more than 12 and less than 14, we conclude:
- All of these options are valid.
Thus, the correct answer is indeed option 'D'. Each option satisfies the condition set out in the problem, confirming that they are all within the required range.

Janani Desai answered |
Calculation of Total Chocolates:
To find out the total number of chocolates Julia and Amelia have together, we need to add the number of chocolates each of them has.
Given Data:
Julia's chocolates = 25
Amelia's chocolates = 65
Calculation:
Total chocolates = Julia's chocolates + Amelia's chocolates
Total chocolates = 25 + 65
Total chocolates = 90
Therefore, the total number of chocolates Julia and Amelia have together is 90 chocolates.
Correct Answer: b) 90 chocolates

Amit Khanna answered |
P = 389 – 82 = 307
Q = 795 – 375 = 420
R = 227 – 29 = 198
S = 963 – 656 = 307
Hence P and S are equal
Q = 795 – 375 = 420
R = 227 – 29 = 198
S = 963 – 656 = 307
Hence P and S are equal
