The basic numbers are quite interesting to us. It has many special qualities. So we have a lot of different aspects of fundamental numbers. Today, I have given such a puzzle. But before that we have seen the technique of solving two simple problems of mathematics. Sum of two numbers 42 The bigger number is 5 times the smaller. Now tell me how many numbers are? We will first look at the solution for this, since the sum of two numbers is 42, again the bigger number is 5 times the smaller, so adding 5 times the number of the smaller number to 1 plus is definitely 42. That is 6 times the small number = 42 Then the smallest number (42/6) = 7 Large number (5 × 7) = 35 See (35 + 7) = 42 We can solve this puzzle easily with the help of algebra. As if I think, number two A and B A big, b small According to condition A = (5 × b). Then, (5 × b) + b = 42, or 6 b = 42, that is, b = (42/6) = 7 So a = 5 × 7 = 35 Large number A = 35 and small number B = 7 (35 + 7) = 42
See another such problem. The difference between the two numbers is 10% of the larger number. What is the big number of the small number 225? To find out the answer, we first get a bigger number. Then A × 10% = (A-225). In other words, (A-A / 10) = 225 Or, (9xc / 10) = 225 So we can say, bigger number is a = (2250/9) = 250. It can be found in many ways.

Last week's puzzle answers
The puzzle was such that: two sequential odd numbers of those whose square is the sum of 32
Answer: Number two 7 and 9
Everyone responded to online comments and e-mails. Thank you all.
How did you answer?
We tested the first and the sequential number of odd numbers. Possible squares are 1, 9, 25, 49, 81, 121 ... etc. Since the sum is 32, so it does not even get as bigger as the square. Now, I can easily test the digits of the numbers, because (81-49) = 32, so the numerical serial odd numbers are two 7 and 9. It is possible to find out the answers given using conventional sources of algebra.
