fifteen years from now ravi age will be four times his present age . what is a present age of ravi
Answers
5 Years
Let us assume the present age of Ravi to be 'x'.
Writing the condition given in the question in words:
Fifteen years after:
15 + Present Age Of Ravi = Present Age Of Ravi x 4
Framing a Linear Equation in one variable based on the condition given in the question we get:
=> x + 15 = 4x
(We assumed the present age of Ravi as x)
Solving the Linear Equation in one variable:
Taking x to the other side of the equation we get:
=> 15 = 4x - x
=> 15 = 3x
Taking 3 to the other side of the equation we get:
=> x = 15 / 3
=> x = 5
Therefore, the value we obtain for 'x' is 5.
Therefore, the present age of Ravi is 5 years because we assumed the age of Ravi to be 'x' and the value we obtained for 'x' is 5.
Answer:
- Let the Present Age of ravi = x years.
- After 15 years age of ravi = (x + 15) years.
❐ According to Question now,
➸ x + 15 = 4x
➸ 15 = 4x - x
➸ 15 = 3x
➸ x = 15/3
➸ x = 5 years
Therefore, Present Age of ravi is 5 years.
