Dear Student

Let the current age of Jaya be x and her daughter be y
According to question,(x-1)=4×(y-1)x-1=4y-4x-4y=-3 
(1)Also, (x+6)-(y+6)=9x+6-y-6=9x-y=9 
(2)Subtracting equation (2) from (1)-3y=-12y=4So, x=13Hence current age of Jaya is 13 years and her daughter is 4 years
The ratio of ages of Jaya to her daughter is 13:4

We hope that this answer solves your query
