I am 3 years younger than my brother. 4 years ago, my brother’s age was 46% of my father’s age and after 3 years, my age will be 90% of my brother’s age. If one-third of my father’s present age is 36% my mother’s present age, then at the time of my birth what was the ratio of my father’s age to my mother’s age?
