Question

If the mean of 2 and 4 is a and mean of 11 and 13 is b, find the value of $\frac{b}{a}$.

• A. 5
• B. 4
• C. 12
• D. 13

Answer 1

The correct option is B

4

Given, mean of 2 and 4 is a and mean of 11 and 13 is b.

$⟹a=\left(\frac{2+4}{2}\right)$

$=3$

and $b=\left(\frac{11+13}{2}\right)$

$=12$

Now, $(\frac{b}{a}=\frac{12}{3})$

$=4$
