Question

arjun is twice as old as Keerthi. Five years ago his age was three times Keerthi’s age. Find their present ages?

Answer 1

Answer:

let the age of keerthi be 'x'

so therefore age of arjun will be 2x

now,according to condition the equation is

x-5=3(2x-5)

x-5=6x-15

-5+15=6x-x

10=5x

x=2

therefore age of keerthi is 2yrs

now,age of arjun is 2x=2×2=4yrs

age of arjun is 4yrs

Answer 2

Step-by-step explanation:

• see this image
• Arjun age x = 2y
• x=2×10
• x=20 years
• Keerthi age y = 10 years
