Question

ages of the ages of Rahul and Haroon are in the ratio 5 is to 7 four years later the sum of their ages will be 56 years what are their present ages

Answer 1

Let the present age of rahul =5x

And the present age of haroon=7x

Before four years

Rahul age was 5x-4
Haroon age was 7x-4

If sum of the ages before four years was 56

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

12x-8=56

12x=48

x=48/12

x=4


Then present age of rahul is 4*5=20 year

And

Present age of haroon is 7*4=28


I hope this much will help you

Answer 2

$\huge{\underline{\bigstar{\sf{solution !!}}}}$

The ages of Rahul and Haroon are in the ratio 5:7

Let Rahul’s present age=5x

Haroon present age=7x

Four years later the sum of their ages will be 56 years. So according to the condition,

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

12x+8=56

12x=56–8

12x=48

x=48/12

x=4

Therefore

$\large{\boxed{\sf{Rahul’s\: present \:age = 5*4=20years}}}$

$\large{\boxed{\sf{Haroon’s\: present \: age =7*4=28years}}}$
