• # question_answer Salaries of Ravi and Sumit are in the ratio 2 : 3. If the salary of each is increased by Rs. 4000. The new ratio becomes 40: 57. What is Sumit's increased salary? A)  Rs. 17000                    B)  Rs. 20,000C)  Rs. 25,500                   D)  Rs. 38,000

(d): Let their salaries be $2x,3x$ $\frac{2x+4000}{3x+4000}=\frac{40}{57}$ $\Rightarrow 114x+4000\times 57=120x+4000\times 40$ $\Rightarrow 4000(57-40)=6x$ $\Rightarrow \frac{4000\times 17}{2}=3x$ $\Rightarrow 34000=3x$             $\therefore 3x+4000=38000/-$
