Answer 1

Answer:

A= 21,250

B= 23,750

Step-by-step explanation:

Given,

Annual income = 3:4 &

annual expenditure = 5:7

There saving 15000 each

therefore let there expenditure be x

so A= 5x and B = 7x

to find value of x

5x+7x = 150000

x = 1250

A= 5x= 5 multiply by 1250(putting x value )

= 6250

B= 7x = 7 multiply be 1250

= 8750

and A income is 15000+6250( saving + expenditure = income )

= 21250

& B income = 8750+15000

= 23750
