⋆ This question says that there are two boys named Rahul and Anshul. The age of Rahul amd Anshul are in ratio of 5 is to 7 that is 5:7 Afterwards this question says that we have to find out that after four years the sum of these ages will be?

${\bigstar \:{\sf{\underline{Given \: that...}}}}$

⋆ The age of Rahul amd Anshul are in ratio of 5:7 (5 is to 7)

${\bigstar \:{\sf{\underline{To \: find...}}}}$

⋆ Four years later the sum of these ages will.

${\bigstar \:{\sf{\underline{Solution...}}}}$

⋆ Four years later the sum of these ages will = 48 years

${\bigstar \:{\sf{\underline{Assumptions...}}}}$

⋆ Let the common ratio be a

⋆ Let age of Rahul be 5a

⋆ Let age of Anshul be 7a

${\bigstar \:{\sf{\underline{Full \; Solution...}}}}$

~ As it's given that the ages of Rahul amd Anshul are in ratio of 5:7 We have already take the assumptions as

⋆ Age of Rahul be 5a

⋆ Age of Anshul be 7a

~ After 4 year's

⋆ Age of Rahul = 5a

→ Age of Rahul = 5(4)

→ Age of Rahul = 5 × 4

→ Age of Rahul = 20 years

⋆ Age of Anshul = 7a

→ Age of Anshul = 7a

→ Age of Anshul = 7(4)

→ Age of Anshul = 28 years

~ It is said that we have to find the sum of ages that's why

→ Sum of ages = Age of Rahul + Age of Anshul

→ Sum of ages = 20 years + 28 years

→ Sum of ages = 48 years

Henceforth, as the age of Rahul amd Anshul are in ratio of 5:7 and four years later the sum of these ages be 48.
