Question

The ages of Rahul and harron are in the ratio of 5:7.four years later the sum of their ages will be 56 years.what are their present age

Answer 1

Answer:

Rahul=20   Harron=28

Step-by-step explanation:

Ratio= 5:7

Let us consider,

Present ages,

Rahul=5x

Harron= 7x

4 years later,

Rahul= 5x+4

Harron= 7x+4

Therefore,

(5x+4)+(7x+4)=56

5x+4+7x+4=56

5x+7x+4+4=56

12x+8=56

12x=56-8

12x=48

x=48/12

x=4

Therefore,

Rahul=5x=5*4=20

Harron= 7x= 7*4= 28

Hope this helped!!!

Answer 2

Let the ages of Rahul and Harron be 5x and 7x.

Now after four years their ages will be 5x +4 and 7x+4.

Now sum of the ages =56 years

Thus (5x+4)+(7x+4)=56

5x+4+7x+4=56

5x+7x+4+4=56

12x+8=56

12x=56-8=48

12x=48

x=48/12=4

5x=5*4=20

7x=7*4=28
