The age of rahul and haroon are in the ratio 5:7 four year later the sum of their age will be 56 years what are the present ages
Answers
Answer:
Rahul = 20 yrs.
Haroon = 28 yrs.
Step-by-step explanation:
Given that ratio of ages of Rahula and Haroon is 5:7
Let, the age of Rahul = 5x yrs.
And, the age of Haroon = 7x yrs.
After 4 years,
Age of Rahul will be = (5x+4) yrs.
Age of Haroon will be = (7x+4) yrs.
But, it's given that,
After 4 yrs their sum of ages will be 56 yrs.
Therefore, we will get,
=> (5x+4)+(7x+4) = 56
=> 12x + 8 = 56
=> 12x = 56 - 8
=> 12x = 28
=> x = 48/12
=> x = 4
Therefore, we will get,
Present age of Rahul = 5×4 = 20 yrs.
Present age of Haroon = 7×4 = 28 yrs.
Hence, the present ages of Rahul and Haroon are 20 yrs. and 28 yrs. respectively.
Answer:
Rahul's age = 20
Haroon's age = 28
Step-by-step explanation:
Let Rahul's age be 5x
Haroon's age be 7x
Four years later age of Rahul = 5x + 4
Four years later age of Haroon = 7x+4
ATQ
(5x + 4) + (7x+4) = 56
5x + 4 + 7x+4 = 56
12x + 8 = 56
12x = 56 - 8
12x = 48
x = 48/12
x = 4
Therefore,
Rahul's age = 5x = 20
Haroon's age = 7x = 28
