Question : Tell me how many numbers are ?

2 day ago i have a question but anyone can't tell me right ans.
Now solved this question---

In mathematics, two numbers are often to be found, where the numbers are related to different conditions. Such as:
You have been asked, two numbers are lasagu = 198, Gasagu = 3 How many numbers are 66 in a number? To find out the answers you need to know a formula of arithmetic. That is, the number of any two numbers lasagu and Gasagu are the same as the product of the two. Then we can say, 198 × 3 = 594 is the product of the number two. As a number 66, the other would be 594/66 = 9 Knowing the formula, this puzzle of mathematics is very easy, is not it?
See another simple account. The question is, an odd number of two digits is divisible by seven. If the number is between 40 and 60, how much is it? To find out the answer, we will see the names of the 7's cell. The multiple digits of 7 between 40 and 60 are 7 × 6 = 42, 7 × 7 = 49 and 7 × 8 = 56. Only 49 of them are odd. So this is the ans.
