Question

mather ages ( x ) doughter = y tather ( 2 x x quad x in x quad|x-x=8| )
( frac{x}{y} cdot frac{13}{4} sum frac{y+4}{x+4}=frac{6}{19} geq 7 x=8+x )
( 4 x=13 y quadleft{frac{y+4}{12+x}=frac{6}{19}right. )
( =34 )

# 8. The ratio of the present ages of mother and daughter is 13:4. Four years hence, the ratio of the ages of daughter and that of father will be 6: 19. If the difference between the ages of father and mother is 8 years, then what will be the ratio of the ages of father and mother six years hence? (1) 7:5 (2) 5:4 (3) 14:11 (4) 9:4 (5) None of these
