Hey!!!!

________

let the age of Marissa be x years and Regan be y years.

Then ATQ,

=> x + 10 = y -----(1)

Also,

After 10 years

=> 80% of y = x

=> 80y/100 = x

=> 4y = 5x

Using (1) in above equation

=> 4(x + 10) = 5x

=> 4x + 40 = 5x

=> x = 40

Thus y = 50.

Thus Marissa is 40 years old and Regan is 50 years old.
