Question

If $2a-5b=0$ then find the value of $\frac{a-b}{b}$

• A. $\frac{7}{2}$
• B. $\frac{3}{2}$
• C. $\frac{5}{2}$
• D. $\frac{7}{5}$

Answer 1

Answer: (B)

$\frac{3}{2}$

Given, $2a-5b=0$
$=>2a=5b$
$=>\frac{a}{b}=\frac{5}{2}$

Now, $\frac{a-b}{b}=\frac{a}{b}-1=\frac{5}{2}-1=\frac{5-2}{2}=\frac{3}{2}$
