Question

Neena’s mother is twice as old as Neena. If sum of their ages is 45 years, find Neena’s
age ?

Answer 1

Answer:

• Neena's age is 15 years old.

Step-by-step explanation:

Let us assume:

• Neena's age = x years

Given that:

• Neena’s mother is twice as old as Neena.

⟼ Neena's mother age = 2x years

• Sum of their ages is 45 years.

⟼ x + 2x = 45

To Find:

• Neena's age.

Finding the Neena's age:

• According to the question.

⟼ x + 2x = 45

⟼ 3x = 45

⟼ 3 × x = 3 × 15

• 3 cancelled both sides.

⟼ x = 15

∴ Neena's age = 15 years

Answer 2

Answer:

Question :-

Neena’s mother is twice as old as Neena. If sum of their ages is 45 years, find Neena’s age ?

Answer :-

• Neena's age = 15 years.

Given :-

• Neena’s mother is twice as old as Neena.
• Sum of their ages is 45 years.

To find :-

• We have to find out the age of Neena.

Step-by-step explanation :-

• Let Neena's age be x years.
• As we are given that, Neena’s mother is twice as old as Neena and the sum of their ages is 45 years.
• So we will take Neena's mother age as 2x years.

$\dag \sf {\underline{According\ to\ the\ question:-}}$

$\sf \mapsto {x\ +\ 2x\ =\ 45}$

$\sf \mapsto {3x\ =\ 45}$

$\sf \mapsto {x\ =\ \cancel \dfrac{45}{3}}$

${\therefore{\underline{\boxed{\frak {Neena's\ age\ =\ 15\ years.}}}}}$
