Answer 1

Total time spent by Pinki to complete the project

$=\frac{5}{6}+\frac{3}{4}+\frac{1}{2}+1\frac{1}{2}$

$$\begin{gathered} =\frac{5}{6}+\frac{3}{4}+\frac{1}{2}+\frac{2\times 1+1}{2} \\ =\frac{5}{6}+\frac{3}{4}+\frac{1}{2}+\frac{3}{2} \\ =\frac{10+9+6+18}{12} \\ =\frac{25+18}{12} \\ =\frac{43}{12} \end{gathered}$$

so Pinki complete complete her project in $3\frac{7}{12}$Hour
