To find: Two digit number that follows the given conditions.
Answer to Problem 27PPE
Required two digit number is 37.
Explanation of Solution
Given information: Any two digit number is calculated as
Concept used: Form two linear equations in two variables a and b, each using giving two conditions given and then solve them for both variables. Then put the values of these variables in two digit number
Calculation: As ones` digit is one more than twice the tens` place digit, so,
Also, as number is two more five times the ones` place digit, so,
By both equations,
By first equation,
So required number is,
Conclusion: It is obtained that required two digit number is 37.
