Question

While coming back home from his school, Kishan covered $4\frac{3}{4}$ km by rickshaw and $1\frac{1}{2}$ km on foot. What is the distance of his house from the school?

Answer 1

Distance from Kishan's house to school = Distance covered by him by rickshaw + Distance covered by him on foot
Thus, we have:
$$\begin{gathered} \left(4\frac{3}{4}+1\frac{1}{2}\right)\mathrm{km} \\ =\left(\frac{19}{4}+\frac{3}{2}\right)\mathrm{km}=\left(\frac{\left(19+6\right)}{4}\right)\mathrm{km}(\mathrm{L}.\mathrm{C}.\mathrm{M}.\mathrm{of}2\mathrm{and}4=(2\times 2)=4)=\left(\frac{25}{4}\right)\mathrm{km}=6\frac{1}{4}\mathrm{km} \end{gathered}$$


Hence, the distance from Kishan's house to school is $6\frac{1}{4}\mathrm{km}$.
