Answer 2

Answer:

Question :-

• Fifteen years from now Ravi’s age will be four times his present age. What is Ravi’s present age?

Given :-

• Fifteen years from now Ravi’s age will be four times his present age.

Find Out :-

• What is Ravi’s present age?

Solution :-

Let Ravi’s present age be x years.

After fifteen years, Ravi’s age = 4x years.

☣ Fifteen years from now,

Ravi’s age = (x+15) years.

So, according to the question or ATQ :-

➙ 4x = x + 15

➙ 4x - x = 15

➙ 3x = 15

➙ x = $\sf \cancel{\dfrac{15}{3}}$

➙ ${\small{\bold{\purple{\underline{x =\: 5\: years}}}}}$

Henceforth, the Ravi’s present age is 5 years .
