Step-by-step explanation:
Let the age of Riya be = x
Then her mother = 7x
Four years from now,
Riya's age will be 4+x
mother's age will be 4+7x
7x+4= 4(x+4) {Given, she will be four times as old as her age.
Expanding the brackets,
7x+4=4x+16
7x-4x= -4+16
3x = 12
x = 4
~Therefore, Riya's age= 4 years
~ Mother's age= 7x = 7×4=28 years
