Let the mother’s age be M and that of her daughter, D, now.

Let the mother’s age be M and that of her daughter, D, now.M = 3D …(1)

Let the mother’s age be M and that of her daughter, D, now.M = 3D …(1)(M-6) = 5(D-6), or

Let the mother’s age be M and that of her daughter, D, now.M = 3D …(1)(M-6) = 5(D-6), orM = 6+5D-30, or

Let the mother’s age be M and that of her daughter, D, now.M = 3D …(1)(M-6) = 5(D-6), orM = 6+5D-30, orM = 5D-24 …(2)

Let the mother’s age be M and that of her daughter, D, now.M = 3D …(1)(M-6) = 5(D-6), orM = 6+5D-30, orM = 5D-24 …(2)Equate (1) and (2)

Let the mother’s age be M and that of her daughter, D, now.M = 3D …(1)(M-6) = 5(D-6), orM = 6+5D-30, orM = 5D-24 …(2)Equate (1) and (2)3D = 5D-24, or

Let the mother’s age be M and that of her daughter, D, now.M = 3D …(1)(M-6) = 5(D-6), orM = 6+5D-30, orM = 5D-24 …(2)Equate (1) and (2)3D = 5D-24, or2D = 24, or

Let the mother’s age be M and that of her daughter, D, now.M = 3D …(1)(M-6) = 5(D-6), orM = 6+5D-30, orM = 5D-24 …(2)Equate (1) and (2)3D = 5D-24, or2D = 24, orD = 12.

Let the mother’s age be M and that of her daughter, D, now.M = 3D …(1)(M-6) = 5(D-6), orM = 6+5D-30, orM = 5D-24 …(2)Equate (1) and (2)3D = 5D-24, or2D = 24, orD = 12.So the Mother is 36 years and the Daughter is 12 years old now.
