Answer:
30
Step-by-step explanation:
3:1
daughter=10
mother=30
solution:-
Given that the ratio of ages of the mother and her daughter at present is 13 : 4
Let the ages of the mother and her daughter at present be 13x and 4x respectively
Six years hence, the ratio will be 5 : 2
Therefore:-
On solving for "x" we get,
26x + 12 = 20x + 30
26x – 20x = 30 -12
6x = 18
x = 18 ÷ 6 = 3
Therefore value of "x" is 3
Present age of mother = 13x = 13(3) = 39 years old
Present age of daughter = 4x = 4(3) = 12 years old
Hope it helps you !!!!
