Arjun is twice as old as shriya. if five years ago his age was three times shriya's age then what is Arjun's present age ? ​

Answer 1

Step-by-step explanation:

The age of Shriya = y - 5. According to the question, five years ago Arjun's age was 3 times the age of Shriya. This gives us the second relation and we obtain equation (2). Hence, the present age of Arjun is 20 years and the present age of Shriya is 10 years.

Hope its help..

Answer 2

Answer:

let age of Arjun be ′x′ and age of Shriya be ′y′

then according to question x=2y−−−(1)

and five years ago 

x−5=3(y−5)

x−5=3y−15

x−3y+10=0−−−(2)

using eq(1)

2y−3y+10=0

y=10

and x=20

∴ age of Arjun is 20 and age of Shriya is 10
