Question

The ages of Hari and Harry are in the
ratio 57. Four years from now the ratio of
their ages will be 3:4. Find their present
ages.​

Answer 1

Answer:

present age of Hari=20 years.

Present age of Harry=28 years

Step-by-step explanation:

The ratio of Hari's and Harry's present ages is 5:7

So, let their ages be 5x and 7x

After 4 years their ages will be in ratio 3:4

Therefore,(5x+4)/(7x+4)=3/4

or, 4(5x+4)=3(7x+4)

or, 20x+16=21x+12

or, 16−12=21x−20x

or, 4=1x

or, x=4

Therefore, present age of Hari = 5x=(5×4)=20 years.

Present age of Harry =7x=(7×4)=28 years

The sum of their age is 28+20=48years

Answer 2

Answer:

Let the ages be 5x and 7x.

Now,

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

= 3(5x+4) = 4(7x+4)

= 15x+12 = 28x +16

= 15x-28x = 16-12

= -13x = 4

= x = -4/13
