Question

The ages of rahul and haroon are in the ratio 3:4 .three years later the sum of their ages will be 57years. What are their present ages?

Answer 1

Answer:

Rahul's age=20 years

Haroon's age = 28years

Step-by-step explanation:

Given information-

The ratio of present ages of rahul and Haroon as 5:7 = 5x=7x

The sum of their ages 4 years later is 56 years

To find -

A/Q (5x+4) +(7x+4)=56

12x=48

x=48/12

x=4

Rahul's age =5x=5×4=20 years

Haroon's age =7×4=28 years

I HOPE THIS IS HELPFUL TO YOU

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
