JASON'S SALARY AND KAREN'S SALARY WERE EACH P PERCENT GREATER IN 1998 THAN IN 1995. WHAT IS THE VALUE OF P?

1. IN 1995 KAREN'S SALARY WAS 2,000 GREATER THAN JASON'S

2. IN 1998 KAREN'S SALARY WAS 2,400 GREATER THAN JASON'S

Let salary ke K and J resp in 95.
In 98 (P+100/P)xK and (P+100/P)xJ resp.
1:- K= 2000 + J .insuff.
2:-(P+100/P)xK =(P+100/P)xJ +2400 insuff

Combining, 2 eqns, 3 variables. insuff. E.
It takes time and effort to explain, so if my comment helped you please press Thanks button :)



Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.

Say initial salary of Jason was j and that of Karen was k

1. k-j = 2000 is not sufficient
2. k(1+p/100) - j(1+p/100) = 2400
=> (k-j) (1+p/100) = 2400
Insufficient

Combining, 2000*(1+p/100) =2400

good enough to find out p
