Question

Arjun is thrice as old as Shriya. Five years ago his age was four times Shriya’s age (five years ago). If Shriya’s present age is x years, then the linear equation so formed can be represented as _________________ .​

Answer 1

Answer:

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

Answer 2

Shriya's age is X

so Arjun age is 3x.

Five years ago shriya's age ( x-5).

Then the five years ago Arjun's age ( 3x-5)

By the question

3x-5 = 4*(x-5)

Which is the linear equation
