Question

The age of rahul and laxmi are in ratio 5:7 Four years later,the sum of their ages will be 56 years. what their present ages?

Answer 1

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

What is the formula of age problem?

• Important Statements and Equations for "Problems based on Ages".
• If the present age is y, then n times the present age = ny.
• If the present age is x, then age n years later/hence = x + n.

How do you answer age problems?

• Create an equation based on the information provided.
• Solve for the unknown variable.
• Substitute our answer back into the equation to see if the left side of the equation equals the right side of the equation.

According to the question:

Age Of Rahul =5x.

age of laxmi=7x.

four years later.

Age of rahul=5x+4.

Age of laxmi=7x+4.

Sum of their ages=56.

5x+4+7x+4=56.

12x+8=56.

12x=48.

x=4.

Age of rahul=4 x 5.

=20.

Age of laxmi=4 x 7 .

=28.

Hence, The present ages of  rahul and laxmi is, 20 and 28.
