The ages of Ravi and Shanu are in the ratio 5:7. Four years from now the ratio of their ages will
be 3:4. Fond their present ages.​

Answer 1

Answer:

Step-by-step explanation:

Let their age be 5x and 7x respectively.

Therefore,according to the question:

5x+4+7x+4=3x+4x

=12x+8=7x

=12x-7x=8

5x=8

x=8/5

Therefore,5x=5*8/5=5

7x=7*8/5=11.2

Therefore Ravi is 5 year old and Shanu is 11.2 years old.

Answer 2

Answer:

ravi age is 20

Shanu age is 28

Step-by-step explanation:

first we should convert the ration into fraction by considering the ages as 5x and 7x

and frame the given equation ,

5x +4/7x+4=3x/4x

5x+4=3x/4x×(7x+4)

=5X+4=21x

=4=21x-5x=16x

X=16/4

X=4

ravi age is 5x so 5×4 =20 years

Shanu age is 7x so 7 ×4 =28years
