Answer:
Let the greater no. be x and the smaller no. be y
The difference between two nos. is 9 so x - 9 = y
Two nos. are in ratio 4:7
Equation no. 1 is
x - 9 = y
x - y = 9.......... 1)
Equation no. 2 is
x / y = 4 / 7
7x - 4y = 0..............2)
Multiplying equation 1) with 4 , we get
4x - 4y = 36.............3)
By subtracting eq.2) from eq.3) ,we get
3x = 36
x = 36/3
x = 12
Put value of x in eq. 1)
x - y = 9
12 - y = 9
y = 12 - 9
y = 3
The two numbers are 12 and 3.
