Question

Ankita's age is twice Radha's age plus $2$ more. Write an algebraic expression to represent Ankita's age, if Radha's age is represented by $x$. Also, find Ankita's age when Radha's age is $8$ years.

• A. Ankita's age $=x+2$, $10$ years
• B. Ankita's age $=2x+2$, $18$ years
• C. Ankita's age $=2x+2$, $10$ years
• D. Ankita's age $=2x-2$, $14$ years

Answer 1

The correct option is B Ankita's age $=2x+2$, $18$ years

Given, Radha's age $=x$ years

Hence, Ankita's age $=2x+2$

When Radha is $8$ years old,

Ankita's age $=2\times 8+2$
$=16+2=18$ years.
