解析 There are 400 odd numbers between 200 and 1000. and there are 100 multiples of 5 less than 500 (including zero). But the two cases overlap-from 200 to 500 there are 30 odd numbers that are multiples of 5. Hence Total = 400 + 100 - 30 = 470. ...
Odd Natural Numbers Odd natural numbers mean natural numbers that are odd numbers. We know thatnatural numbersare positive counting numbers that start from 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and go on till infinity. Among these if we select the odd numbers, we get 1, 3...

When we subtract two even numbers, the result is always an even number. For example, when we subtract 8 from 14 we will get 14 – 8 = 6. Similarly, when we subtract 24 from 36, we will get 36 – 24 = 12. When we add an even number and an odd number, the result is always ...
