Answer:
Her mother is 35 years
Step-by-step explanation:
Let her present age be x
10 years ago the age will be x-10
From the question;
x = 3(x-10) ••••(i)
Her mother’s age at that time is (x-10+20) = x + 10
so we want her mother’ s age now
from equation i
x = 3x - 30
3x - x = 30
2x = 30
x = 30/2
x = 15
her mother’s age then is 15 + 10 = 25
Her age now will be 25 + 10 = 35 years
