The ratio of the age of a gentleman and his wife is 4 : 3. After 4 years this ratio will be 9 : 7. If at the time of their marriage the ratio was 5 : 3, how many years ago they were married? Pick:
A) 10 years  B) 8 years  C) 12 years  D) 15 years  E) 17 years
Let the present age of gentleman (G) and wife (W) be 4x and 3x resp....   thus after 4 yrs the ratio will be (4x+4)/(3x+4)=9:7..   on solving we get the value as x=8..i.e present ages are G=32,W=24...   Now at the time of marriage the ratio will be :   (32-y)/(24-y)=5:3   on solving we get y=12...   Thus 12 yrs ago they got married.   ANSWER:12 years
