Question

Q 5. The sum of the ages of a daughter and mother is 56 years; after four years the age of the mother will be three times that of the daughter. What is the age of the daughter and the mother respectively?

12 years, 41 years12 years, 30 years11 years, 34 years12 years, 44 years21 years, 42 years​

Answer 1

Let daughter's age be x years.

Then, mother's age = 3x years

$(3x + 12) = 2(x + 12) \\ (3x + 12) = 2x + 24 \\ x = 12$

Daughter's age today = 12 years And the mother age is = (56 - 12) = 44 years

Answer 2

Answer:

Let the age of daughter be 'x' years

and mother's age = (56 - x) years

After 4 years:

daughter's age = (x+4) years

mother's age =(56-x+4)= (60-x) years

According to the question:

3(x+4)=60-x

=>3 x + 12 = 60 - x

=>3x+x= 60-12

=>4x= 48

=> x= 4

My answer is different:(
