Answer 1

Hlw mate!!
_______________________________________________________
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

Answer


Let the  Number 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 96 or 69
