Question

The ages of rahul and haroon are in the ratio 5:7. For years later the sum of their ages will be 56.what are their present ages

Answer 1

Step-by-step explanation:

given,

rahul : haroon = 5:7

rahul age be 5x

haroon age be 7x

after 4 years

rahul age + haroon age = 56

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

=> 12x +8 = 56

=> 12x = 48

=> x =4

age of rahul = 5x = 5*4 = 20

age of haroon = 7x = 7*4 =28

The age of Rahul and Haroon are in the ratio 5:7. Four years later the sum of ages will be 56 years. What are their present ages?

${\huge{\fcolorbox{cyan}{lime}{\fcolorbox{yellow}{blue}{\sf{\color{yellow}{AnsWer:- }}}}}}$

Let the current age of Rahul and Haroon be 5x and 7x respectively

Four years later their ages become 5x + 4 and 7x + 4 respectively.

According to the question,

5x + 4 +7x + 4 = 56

or 12x + 8 = 56

Transposing 8 to the RHS we get,

12x = 48

Dividing both sides by 12 gives,

x = 48/12 = 4

Thus current age of Rahul = 5*4 = 20

Haroon = 7*4 = 28
