Arithmetic Aptitude :: Problems on Ages
10. Sharla married 6 years ago. Today her age is 5/4 times her age at the time of her marriage. Her daughter age is 1/5 of her age. What is the ratio of Sharla age to her daughter age after 6 years?
Lets sharla present age = x year.
So as per the question:
x = (5/4)*(x - 6)
=> 4x = (5x - 30)
x = 30 years.
So her daughter age = 30/5 years = 6 years.
After 6 years their ratio will be = 36/12 = 3:1
