Question

Deepika is twice as old as his brother Vikas if the difference of their age be 11 years find their present age

Answer 1

Answer:

• Present age of Deepika = 22 yrs
• Present age of Vikas = 11 yrs

Explanation:

Let,

Present age of Deepika = x

and, Present age of her brother Vikas = y

Then, as given that; Deepika is twice as old as her brother Vikas

therefore,

→ Age of Deepika = 2 ( Age of Vikas )

→ x = 2 y  ___equation (1)

Also given that; Difference of their ages be 11 yrs

therefore,

→ (Age of Deepika) - (Age of Vikas) = 11

→ x - y = 11

Using equation (1)

→ ( 2 y ) - y = 11

→ y = 11

Putting value of y in equation (1)

→ x = 2 y

→ x = 2 ( 11 )

→ x = 22

Therefore,

• Present age of Deepika = 22 yrs. and
• Present age of Vikas = 11 yrs.

Answer 2

Answer:

✳️ Given ✳️

$\mapsto$ Deepika is twice as old as his brother Vikas. If the difference of their age be 11 years .

✳️ To Find ✳️

• $\mapsto$ What is the value of their present age.

✳️ Solution ✳️

✒️ Let the present age of Vikas be x years

✒️ Since, Deepika is twice as old as Vikas, then the present age of Deepika will be 2x years

➕ According to the question ,

$\implies$ 2x - x = 11

$\dashrightarrow$ x = 11

$\therefore$ ✴️ Present age of Vikas = 11 years.

✴️ Present age of Deepika = 2x = 2(11) = 22 years.
