Question

ratio of salaries of two person is 9 ratio 7 and their expenditure is 4 ratio 3 if everyone has 2000 rupees savings then find their monthly salary​

Answer 1

9A-4B=2000 ------------eq(1), ×3

7A-3B=2000 ------------eq(2), ×4

27A-12B=6000,

28A-12B=8000,

now solving these two equations we have

A=2000,

therefore

A's salary=9×2000=₹18000,

B's salary=7×2000=₹14000
