Dear Student
Let the monthly income of A and B be 5x and 6x
And, let their expenditure be 3y and 4y
Savings of A=5x-3y
Savings of B=6x-4y
Amount saved by A=1800
5x-3y=1800.......(1)
Amount saved by B=6x-4y=1600...........(2)
Solving equation 1 and 2
we will get the value of x and y
For the monthly income of B=6x
