16. The result of dividing a number of two digits by the number with digits reversed is
I — . If the sum of digits is 12, find the number.
16. Lets the tens and units digits be x and y
the original number is 10x+y
but sum of digits is 12
so ,x+y=12
y=12-x
Now,
the original number is 10x+ 12-x=9x+12
the reversed number is 10(12-x) +x= 120-9x
9x+12/120-9x=7/4
so,99x = 792,
x=8,
y=12-8=4
so original number is 84
