Question

18 years from now Ravi's age will be 4 times his present age. What is Ravi's present age.​

Answer 1

Answer:

Let Ravi's present age be x.

It is given that, after 18 years Ravi's age with be 4 times present age.

Hence, that means, after 18 years, Ravi's age will be 4 times x.

Now, forming an equation.

Condition 1:- After 18 years.

Equation:- x + 18

The other part of the equation,

Condition 2:- Four times present age.

Equation:- 4x

Hence, full Equation: x + 18 = 4x.

Solving it,

➸ x + 18 = 4x

➸ 18 = 4x - x

➸ 3x = 18

➸ x = 18/3

➸ x = 6

Hence, the present age of Ravi is 6 years.

Age of Ravi after 18 years will be x + 18 = 6 + 18 = 24 years.

VERIFICATION–

➸ 24 = 4x

➸ x = 24/4

➸ x = 12/2

➸ x = 6

Hence, the answer we found is correct.

Answer 2

Step-by-step explanation:

$\bf \huge Question \: \:$

• 18 years from now Ravi's age will be 4 times his present age. What is Ravi's present age.

_________________________

$\bf \huge Given \: \:$

• , after 18 years Ravi's age with be 4 times present age.

__________________________

$\bf \huge \:To \: Find$

• What is Ravi's present age.

__________________________

Supposed Ravi's present age be x.

Then Accourding To the Question :-

after 18 years, Ravi's age will be 4 times x.

We know,

• After 18 years.

Then 1 Equation is x + 18 ............Equ.1

• 4times present age.

Then Equation 2 is 4x . .......equ. 2

Accourding to the Question

18 years from now Ravi's age will be 4 times his present age

Then Putting the Equation :-

$\bf \:x + 18 = 4x.\: \:$

On Solving

$\bf \:X-4x = - 18\: \:$

$\bf \:-3 x = -18\: \:$

$\bf \: 3x = 18\: \:$

$\bf \: x \: = \frac{18}{3} \\ \\ \bf \red{\:x = 6}$

The present age of Ravi is 6 years.
