Question

Peter's age in $10$ years will be $12$ less than $4$ times his current age. What is Peter's current age (in years)?

• A. $7.33$
• B. $7.71$
• C. $6.04$
• D. $6.49$

Answer 1

The correct option is A $7.33$

Let Peter's current age be $x$ years

According to question,

$\Rightarrow$$(x+10)=4x-12$

$\Rightarrow$$4x-(x+10)=12$

$\Rightarrow$$4x-x-10=12$

$\Rightarrow$ $3x=22$

$\Rightarrow$$x=\frac{22}{3}=7.33$

Peter's age $=7.33$ years
