Question

laxmi father is 49 years old.He is 4years older than three times of laxmi's age.What is laxmi's age​

Answer 1

Step-by-step explanation:

Let the age of Laxmi be x. So,

3x + 4 = 49

or 3x = 49 - 4

or x = 45/3

or x = 15.

So Laxmi's age is 15 years. For checking, we can find the age of Laxmi's father's age. So, to do this we would first multiply 15 with 3 which is 45 and in the question it is written that he is 4 years older than three times of laxmi's age. So, by adding 4 to 45 if the age of Laxmi's father's age arrives then our answer is correct.

Answer 2

★GIVEN:

• Laxmi's father's age=49 years

• laxmi's father is 4 years older than three times of laxmi's age.

★TO FIND:

• laxmi's age=?

★SOLUTION:

Let the laxmi's age be x years and he father's age be y years.

Therefore,

From given condition,

y=3x+4

But her father's age is given.

So, 49=3x+4

: . 49-4=3x

: . 45=3x

: . x=45/3

: . x=15

♠︎ Therefore laxmi's age is 15 years.

★Verification:

We have taken laxmi's age is x years and thar of her father is y years

: . From given condition we have taken,

y=3x+4

Here, L. H. S=y=49

R. H. S=3x+4=3(15) +4=49

So,

L. H. S =R.H.S
