Question

Out of the total of $\frac{18}{13}$ work, Nancy did $\frac{7}{13}$, and Nexus did $\frac{5}{13}$. The remaining work was done by Prof. Burgurs. How much work did he do?

• A. $\frac{4}{13}$
• B. $\frac{7}{13}$
• C. $\frac{5}{13}$
• D. $\frac{6}{13}$

Answer 1

The correct option is D $\frac{6}{13}$

Total work = $\frac{18}{13}$
Nancy did $\frac{7}{13}$ of the work.
So, the remaining work is:
$\frac{18}{13}-\frac{7}{13}=\frac{18-7}{13}=\frac{11}{13}$
From this, Nexus did $\frac{5}{13}$ of the work.
So, the remaining work is:
$\frac{11}{13}-\frac{5}{13}=\frac{11-5}{13}=\frac{6}{13}$
This is the work was done by Prof. Burgers.
