Answer 2

Hi Dear !
___________________________________________________________
let one no. x 
another be y 
ATQ x+y =240________(1)
x/y=3/5
3y=5x
y=5x/3______________(2)
putting value of y in Eqn (1)
we get,
x+5x/3  =240
3x+5x/3=240
8x/3      =240
8x         =720
x           =90
so , y = 240-x = 240 - 90 = 150 
Another method :
Let one no x 
then another No be 240-x 
Also x/240-x= 3/5 
        5x         = 720 - 3x 
        8x         = 720 
          x         = 90 
  then 240-x = 150 
SO, the two numbers are 150 and 90
