The monthly income of Rita and Bishwant are in the ratio of 4 : 3 and their expenses are in the ratio 3 : 2.
If Rita earns an amount 4x, Bishant earns 3x. If Rita spends 3y, Bishant spends 2y. The amount saved by the two is equal to $2000
=> 4x - 3y = 2000 and 3x - 2y = 2000
Subtracting the two equations x - y = 0 or x = y
Substituting this in 4x - 3y = 2000
=> x = 2000
The amount earned by Rita is 4x = 8000 and Bishant earns 3x = 6000
The monthly income of Rita is $8000 and that of Bishant is $6000.
