Solution ✌️
- Let the no. as = 4x , 5x
after subtracting the ratio become 3:4 so let them as 3x and 4x
- So the equation formed here is
- 4x -9 +5x - 9 = 3x , 4x
- 9x - 18 = 7x
- 9x -7x = 18
- 2x = 18
- X = 18 ÷ 2
- x= 9
So , put the value of X in 4x and 5x
therefore the ans will be
4x=4*9=36
5x= 5*9 = 45
Answer ✌️= 36 , 45
Thanks ✌️
