Question

The ages of Rahul and Laxmi is the ratio 5:7 . Four years later , the sum of their ages will be 56 years . What are their present ages ​

Answer 1

Answer:

Age of Rahul and Laxmi is 20 and 28 years respectively.

Step-by-step explanation:

Let the age of laxmi be 7x

and rahul age be 5x

ATQ

after three year the sum of their age is 56

Then,

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

5x+4+7x+4=56

12x+8=56

12x=56-8

x=48÷12

x=4

so,the current age

age of rahul=5x=5×4=20 years

age of laxmi=7x=7×4=28 years

Answer 2

Answer:-

20 years and 28 years

Step-by-step explanation:

Let the present ages of Rahul and Laxmi be 5x and 7x years.Then,

After four years :-

Age of Rahul = 5x+4 years

Age of Laxmi = 7x+4 years

Now,

5x+4+7x+4 = 56

12x+8 = 56

12x = 56-8

12x = 48

x = 48/12

x = 4

Present age of Rahul :-

= 5x years

= 5×4 years

= 20 years

Present age of Laxmi:-

= 7x years

= 7×4 years

= 28 years
