Answer 1

Answer:

Option-- A

Step-by-step explanation:

Let  their present age be 4x & 3x.

Then, after 4years the husband's age =4x+4 and the wife's age =3x+4.

So, by the given condition,

3x+44x+4=79⟹28x+28=27x+36⟹x=8.

Then the present age of the husband=4×8years=32years &

the wife's age=3×8years=24years.

Let their marriage took place P years back.

Then, by the given condition,

24−P32−P=35⟹96−3P=120−5P⟹2P=24⟹P=12yrs.
