St 1
Rita = 2/3 J
4000 = 2/3 J
12000/ 2 = J
J = 6000
Combined Salary = 10,000 Sufficient

St 2. If Ritas Salary is 6000
6000 = 2/3J
J = 9000
Total = 15000
If Juanitas Salary = 6000.
Rita = 6000×2/3 = 4000
Total = 10000
NS

Ans A

Rita is 2x and J is 3x
(1) gives us 2x=4000..hence 5x= 10000
Sufficient

(2) if 2x = 6000 then 5x is 15000
If 3x = 6000 then 5x is 10000

Not sufficient

Hence A
