Answer:
The digits are 4and 8.hence, the no. is 84.
Step-by-step explanation:
Let the digit at unit place be x and at tens place be y.
By the given condition
1) x:y= 1:2
x/y = 1/2 .......(1)
2) y+x = 12 .........(2)
Now, from eq(2)
y+x = 12
y= 12-x....... (3)
substitute (3) in (1)
x/ 12-x =1/2
2x = 12- x
3x = 12
x= 4
y= 12- 4
y= 8
