Brandon is 5 years younger than jhonny .after ten years jhonny will be twice of as brandon was 5 years ago ,find their present ages
Answers
Answer:
Jhonny = 30 yrs.
Brandon = 25 yrs.
Step-by-step explanation:
Let the present age of Jhonny is x yrs.
Therefore, we have,
The present age of Brandon = (x-5) yrs.
After 10 yrs.,
Age of Jhonny = (x+10) yrs.
5 yrs. ago,
Age of Brandon = (x-5-5) = (x-10) yrs.
But, it's given that,
After 10 yrs. Jhonny will be twice of as Brandon was 5 yrs. ago.
Therefore, we have,
=> x + 10 = 2(x-10)
=> x + 10 = 2x - 20
=> 2x - x = 10 + 20
=> x = 30
Therefore, we have,
=> x - 5 = 30-5 = 25
Hence, the presen ages of Jhonny and Brandon are 30 yrs. and 25 yrs. respectively.
Answer: Present ages of Brandon and Johnny are 25 and 30 years respectively.
Let the age of Johnny be x, then age of Brandon = x - 5.
According to ques,
After ten years , johnny will be twice of as brandon was 5 years ago
x + 10 = 2(x -10)
x + 10 = 2x - 20
10 + 20 = 2x - x
x = 30
==>> present age of Johnny = x = 30 years
And present age of Brandon = x - 5 = 30 - 5 = 25 years.
Present ages of Brandon and Johnny are 25 and 30 years respectively.
