Answer:
Let income of a be 3r and b be 2r
and according to the question their investment be 5y and 3y respectively.
ATQ........
3x - 5y = 1000 ......... (1)
2x - 3y =1000.......... (2)
x = [1000+3y]/ 2 (from eq 2)
putting the value of x in eq 1 we ge :-
3* [1000+3y]/2 - 5y = 1000
=> y = 1000
x =( 1000 + 3000 )/ 2
= 2000
income of b = 2x = 4000
