Answer:
It will take 13 years to Ishaan age will be 5 times William age.
Step-by-step explanation:
Given : Ishaan is 72 years old and William is 4 years old.
To find : How many years will it take until Ishaan is only 5 times as old as William?
Solution :
Let x be years since today.
According to question,
Ishaan's age is I=72+x
William's age is W=4+x
Now, We want the time for Ishaan age will be 5 times William's age:
i.e. [tex]I=5W[/tex]
[tex]72+x=5(4+x)[/tex]
[tex]72+x=20+5x[/tex]
[tex]72-20=5x-x[/tex]
[tex]52=4x[/tex]
[tex]x=13[/tex]
It will take 13 years to Ishaan age will be 5 times William age.
By this time William will be 17 years old and Ishaan will be 85 years old.
It will take 13 years to Ishaan age will be 5 times William age.
Given that,
- Ishaan is 72 years old and William is 4 years old.
Based on the above information, the calculation is as follows:
Let x be years since today.
So,
Ishaan's age is I=72+x
William's age is W=4+x
Now
I = 5W
72 +x = 5(4 + x)
72 + x = 20 + 5x
52 = 4x
x = 13
