let priya Present age be x years and her mother's Present age be y years;;;;

( y-10 )= 5*( x -10 ) and  x= (3/7)*y

solving we get x= 15 , y = 35 ,,
so after 5 years x= 20 , she will be half of her mother's age

When Maya went to get a passport, she had to give her real date of birth, but under all other circumstances she refused. When somebody asked how old she was, she said she was twenty-one, mentally omitting all Sundays. Sundays she didn't work, so naturally she didn't get any older.

How old was Maya really?
