This has no answer. Any five odd numbers will always add to an odd number. 100 is even.
Well, isn't that a happy little math problem! Let's think about it together. The two numbers are 7 and 93. When you add them together, you get 100, and if you multiply that sum by 21, you'll get 2100. Just like painting a beautiful landscape, sometimes all we need is a little patience and a touch of creativity to solve a problem.

Multiply 2100 by 0.3 You can also do it this was- 30% is 30 for each 100- and you have 21 100's. 30 X 21. Or 3X 21 (63) and add a zero.

Instead of adding each digit in turn, acknowledge that there are 100 numbers to add, and then multiply that by the average of 1 and 100.Ie. 100×(1+100)÷2=100×101;÷2100×101;÷2=50×101=5050So, in short, the answer is: 5050
