Answer 2

Answer :–

• Lakshmi is 15 years old.

Given :–

• Lakshmi father is 49 year old.
• He is 4 year older than three times of Lakshmi's age.

To Find :–

• Lakshmi's age.

Solution :–

• Let Lakshmi's age be x.

• And she is older than three times means 3x.

And Lakshmi's father age = 4 + 3x Lakshmi's age.

On substitution.

we get,

→ 49 = 4 + 3x

→ 49 - 4 = 3x

→ 45 = 3x

→ $\frac{\cancel{45}}{\cancel3}$ = x

Cut the numerator and the denominator with 3.

So, we get

→ $\frac{15}{1}$ = x

It means,

→ 15 = x

We take x as a Lakshmi's age.

That's why lakshmi's age is 15 years.

Hence,

Lakshmi's age is 15 years.
