Find all natural numbers having two digit , knowing that twice the units digit 1 more than the ten digit , and if we write that two digits in reverse order, we get a new number which is 27 less than the old one
Tell the numbers to find are \(\overline{ab}\)
\(\Rightarrow\left\{{}\begin{matrix}2b-a=1\\\overline{ab}-\overline{ba}=27\end{matrix}\right.\)
=> 10a + b - 10b - a = 27
=> 9a - 9b = 27
=> a-b = 3
=> a = b + 3
=> 2b - 1 = b+3
=> 2b - b = 3 + 1
=> b = 4
=> a = \(2\cdot4-1=7\)
So he number to find is 74

The average of three numbers are 32.The second number is two times the fist numbers and the third number is six units more than the second number.The first number is?
Dịch: Trung bình cộng của 3 số là 32. Số thứ hai gấp 2 lần số thứ nhất, số thứ ba hơn số thứ hai 6 đơn vị. Tìm số thứ nhất?
Tổng 3 số bằng: 32 x 3 = 96
Coi số thứ nhất là 1 phần, số thứ hai là 2 phần như vậy, Số thứ ba là 2 phần và 6 đơn vị
Ta có sơ đồ sau:
Bớt số thứ hai đi 2 đơn vị
Tổng số phần bằng nhau là: 1 + 2+ 2 = 5 (phần)
5 phần ứng với 96 - 6 = 90 đơn vị
Số thứ nhất là: 90 : 5 x 1 = 18
ĐS: 18
