Question

the ten's digit of a two digit number is half the digit at ones place. if the digits are interchanged,the resulting number is 36 more to the original number. find the number​

Answer 1

Step-by-step explanation:

let the unit digit of no be x and tenth digit be x/2

number=10(x/2)+x

after interchanging the digit no is 10x+ x/2

(A/Q)

10X+X/2= 10(X/2)+X+36

21X/2 = 10X / 2 + X +36

21X/2 = 6x +36

21x/2-6x= 36

(21x - 12x)/2 = 36

9x/2= 36

x = 36×2/9

x=8

the no is =

10(x/2)+x=10(8/2)+8=40+8=48

so ,48 is the answer
