Find the present ages of mother and daughter. sister​

Answer 1

Answer:

your answer is:

Step-by-step explanation:

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

M = 3D …(1)

(M-6) = 5(D-6), or

M = 6+5D-30, or

M = 5D-24 …(2)

Equate (1) and (2)

3D = 5D-24, or

2D = 24, or

D = 12.

So the Mother is 36 years and the Daughter is 12 years old now.

Answer 2

Let the present age of mother and daughter be x and y respectively.

x=3y---(1)

(x-6) = 5(y-6)

x-6 = 5y -30

x = 5y-24----(2)

x=3y (from (1)

5y-24=3y [ substituting x from (2)]

5y-3y=24

2y=24

y=12

x =3y

x= 3×12

x= 36
