Hi Dear !
_______________________________________________________
Let the No. Be xy
ATGC ,
xy + yx = 165
10x + y + 10y+x = 165
11x + 11y = 165
Divide Both sides By 11
x + y = 15 __________(1)
Also,x - y = 3 ____________(2)
By 1 and 2 we get
2x = 18
x = 9
y = 6
so the number is
So the number is 96 or 69
