10 years ago the age of the father was 5 times that of the son. 20 years hence the age of the father will be twice that of the son. The present age of the father (in years) is

The graphs of $$2x+3y-6=0, 4x-3y-6=0, x=2$$ and $$ \displaystyle  y=\dfrac{2}{3}  $$ intersect in 

What values of x and y satisfies the equations  $$\displaystyle \frac{x}{6}+\frac{y}{15}=4$$ and $$\displaystyle \frac{x}{3}-\frac{y}{12}=4\frac{3}{4}$$

The ratio of the ages of A and B ten years before was $$3 : 5$$. The ratio of their present ages is $$2 : 3$$ . Their ages are respectively

In the system of equations $$\dfrac {12}{x+y}+\dfrac {8}{x-y}=8$$ and $$\dfrac {27}{x+y}-\dfrac {12}{x-y}=3$$, the values of $$x$$ and $$y$$ will be
