Question

at the time of wedding the brides age was 3/4 of the grooms age .after 8 years her age is 4/5 of her husband's age. find the age of the bride at the time of our wedding

Answer 1

Let groom's age be x
then' bride's age be 3x/4
bride's age after 8 years=3x/4 +8
then ,groom's age after 8 years =x+8
3x/4 +8=4/5(x+8)
3x/4 +8=4x/5 + 32/5
3x/4 -4x/5=32/5 - 8
-x/20=-8/5
-x=-8×20/5
=x=32
bride's age after 8years =3×32/4
=24

Answer 2

Answer:

24 years old

Step-by-step explanation:

Define x:

Let the Groom be x years old at the wedding

Bride = 3/4 x

Find the age 8 years later:

Groom = x + 8

Bride = 3/4 x + 8

Solve x:

The Bride is 4/5 the age of the Groom

3/4 x + 8 = 4/5 (x + 8)

3/4 x + 8 = 4/5 x + 32/5

4/5 x - 3/4 x = 8 - 32/5

1/20 x = 8/5

x = 8/5 ÷ 1/20

x = 32

Find the bride's age at the wedding:

Bride = 3/4 x = 3/4 (32) = 24 years old

Answer: The bride was 24 years old at the wedding.
