Question

If $37a=37b=5661$, what is the average of $a$ and $b$?

• A. $74.5$
• B. $151$
• C. $76.5$
• D. $153$

Answer 1

The correct option is D

$153$

Step 1: Given data

As per data given in the question,

We have,

$37a=37b=5661$

Step 2: Calculation

Dividing both side by $37,$

We will get,

$\therefore a=b=\frac{5661}{37}=153--------\left(i\right)$

Step 3: Calculation of Average

As we know that,

Average of $a$ and $b$ will be $=\frac{a+b}{2}$

So, average of $a$ and $b$ will be$=\frac{153+153}{2}=153$

Hence, option (d) is correct choice.
