Question

A student was asked to multiply a certain number by 3 and to add 2 to it, but he divided the number by 3 and subtracted 2 from it and got the number 1. The correct answer is

• A. 9
• B. 25
• C. 29
• D. none of these

Answer 1

The correct option is C 29

Let the certain number be x.
As per problem, the student divided the number by 3 and subtracted 2 from it and got the number 1.
$\Rightarrow \frac{x}{3}-2=1$
$\Rightarrow \frac{x-6}{3}=1$
$\Rightarrow x-6=3$
$\Rightarrow x=9$

Now, in actual the student was asked to multiply the number by 3 and add 2 to it
So, the correct answer will be $9\times 3+2=27+2=29$
