Question

If $A3+8B=150,$then the value of$A+B$ is

• A. $13$
• B. $12$
• C. $17$
• D. $15$

Answer 1

The correct option is A

$13$

Solve for the value of $A+B$

From the question,

$A3+8B150$

In one’s place, we have to add $3+B=0$

Since $B$ is a digit, the value of$B$ should between$0$and $9$

When you substitute the value of $B=7,$ then you will get

$3+7=10$

So here the unit digit is $0$

Now carry $1$to the $10’$s place,

Repeat the same process for $10’$s place, you will get the value of $A$

So,$A=6$

We get,

$$\begin{gathered} A+B=6+7 \\ A+B=13 \end{gathered}$$

The value of $A+B$is $13$

Hence, Option(a) is the correct answer.
