Question

Ratio of income A & B 3:2 and ratio is expenditure 4:3 . If they save respectively 2000 and Rs 900 find their income.

Answer 1

Answer:

Income of A is 7200 and B is 2600

Step-by-step explanation:

lets take x and y

3x-4y=2000 implies 6x-8y=4000

let it be eqn 1

also 2x-3y=900implies 6x-9y=2700

let it be eqn 2

eqn 1-eqn 2

y=1300

thus x=2400

income of A=3x=7200

income of B=2y=2600

Hope everything is clear

Answer 2

let us take the values of x and y

then income of a =3x

that of b=2x

then,expenditure of a=4y

that of b=3y

then we get two eqn

3x -4y=2000

2x-3y=900

if we equate both values we get x=2400

then income of a=3x=7200

then income of b=2x =4800
