Answer 2

Answer:

Rahul = $19\frac{1}{3}$ years old

Laxmi = $28\frac{2}{3}$ years old

Step-by-step explanation:

Ages of Rahul and Laxmi : 5 : 7

4 years later, the sum of their ages will be 56.

Even the years change, their age's ratio will not change.

Let's ignore the 4 years later statement first.

Which means the sum of their ages will be 56, and their ratio is 5 : 7.

You will have to add up the ratio because the ratio's sum is equal to the sum of their ages.

5 + 7 = 12

The ratio sum of their ages is 12, and the sum of their ages is 56.

Now divide the sum of their ages by the ratio total, for you want to find the value of each part.

56 ÷ 12 = $4\frac{2}{3}$

Which means, each part is $4\frac{2}{3}$.

Now you have each part's value, it is now possible to calculate Rahul and Laxmi's ages!

Now lets take back the ratio ( 5 : 7 )

( 5 : 7 ) ( Rahul : Laxmi )

Rahul = 5 × $4\frac{2}{3}$

         = $23\frac{1}{3}$

Laxmi = 7 × $4\frac{2}{3}$

         = $32\frac{2}{3}$

Which means, four years later, their age will be $23\frac{1}{3}$ for Rahul and $32\frac{2}{3}$ for Laxmi.

Now let's input the four years later.

Four years later, their age will be $23\frac{1}{3}$ for Rahul and $32\frac{2}{3}$ for Laxmi.

To calculate their present age, subtract 4 from their ages four years later!

Rahul Present Age = $23\frac{1}{3}$ - 4

                               = $19\frac{1}{3}$

Laxmi Present Age =  $32\frac{2}{3}$ - 4

                               = $28\frac{2}{3}$

So, Rahul's present age is $19\frac{1}{3}$ while Laxmi's present age is $28\frac{2}{3}$.

Your final answer is $19\frac{1}{3}$ for Rahul's present age and $28\frac{2}{3}$ for Laxmi's present age.
