Question

Solve the following equation:

$3m=5m-\frac{8}{5}$

If $m=\frac{4}{n}$, then the value of $n$ is:

• A. $9$
• B. $5$
• C. $2$
• D. $13$

Answer 1

Answer: (B)

$5$

Given: $3m=5m-\frac{8}{5}$

$\Rightarrow 5m-3m=\frac{8}{5}$

$\Rightarrow 2m=\frac{8}{5}$

Divide $2$ on both the sides, we get

$m=\frac{4}{5}$

Comparing this with $m=\frac{4}{n}$, we get $n=5$.
