Question

the tens digit of a two digit number is half the digit at ones place if the digit are interchanged the resulting number is 36 more to the original find the number​

Answer 1

Answer:

Original Number =  48

Step-by-step explanation:

firstly we form the equations on behalf of the conditions given:

(x/2)10 + x = y         -------->1       (10 is multiplied as it is a 10's place)

10x + (x/2) = y + 36 --------->2

now simplified equations :

12x - 2y = 0           ----------->1

21x - 2y = 72          ----------->2

Now solve them simultaneously :

we get x = 8  and y = 48
