• A. 2400
• B. 3200
• C. 5400
• D. none

Answer 1

The correct option is B

3200

Let 4x and 5x be their salaries one year ago

Similarly let 3y,5y be the last year salary and present salary of A and 2z and 3z be the last year salary and present salary of B

By using all the given conditions, we get 5*$\frac{4}{3}\ast x$ +3$\frac{5}{2}$*x=6800 x=480 y=640

So present salary of A=5y=3200
