Answer:
18 year
Step-by-step explanation:
Let the age of her husband be 4a, when she got married, her age 3/4 of 4a.
So, when she got married:
Her age = 3a
Husband's age = 4a
After 12 years:
Her age = 3a + 12
Her husband's age = 4a + 12
In question, that time she is 5/6 of her husband's age.
= > her age = 5/6 of her husband's age
= > 3a + 12 = (5/6) (4a + 12)
= > 6(3a + 12) = 5(4a + 12)
= > 18a + 72 = 20a + 60
= > 72 - 60 = 20a - 18a
= > 12 = 2a
= > 6 = a
Hence, age of swati when she got married was:
3a = 3(6) = 18 year
