Question

The sum of the present ages of the mother and her daughter is 80 years. The mother

was thrice as old as her daughter when she was as old as her daughter is now, Find
the present ages of the mother and her daughter.​

Answer 1

mother=60

daughter=20

Explanation:

present age is 80

mother is thrice as old as her daughter when she was as old as her daughter is now

i.e 3x

then daughter is x

so 3x + x =80

4x =80

4x/4=80/4

then you cancel out with 4

therefore x is 20

mother=3x

3×20=60

then daughter=20

Answer 2

20 and 60

Explanation:

80= 3x + x

80= 4x

x=20

Daughters Age = x = 20

Mothers Age = 3x = 3(20)

=60
