Question

On one day a rickshaw puller earned$\text{Rs. 160}$. Out of his earnings, he spent$\text{Rs.}26\frac{3}{5}$on tea and snacks,$\text{Rs.}50\frac{1}{2}$on food and$\text{Rs.}16\frac{2}{5}$on repairs of the rickshaw. How much did he save on that day?

Answer 1

Step 1: Calculate total expenditure:

Total earning =$\text{Rs. 160}$

Money spent on tea and snacks =$\text{Rs.}26\frac{3}{5}$

Money spent on food =$\text{Rs.}50\frac{1}{2}$

Money spent on repair on the rickshaw =$\text{Rs.}16\frac{2}{5}$

Total expenditure =$26\frac{3}{5}+50\frac{1}{2}+16\frac{2}{5}$

$$\begin{gathered} =\frac{133}{5}+\frac{101}{2}+\frac{82}{5} \\ =\frac{266+505+164}{10} \\ =\frac{935}{10} \end{gathered}$$

Step 2: Calculate total saving:

Total saving = Total earning - Total expenditure

$$\begin{gathered} =160-\frac{935}{10} \\ =\frac{1600-935}{10} \\ =\frac{665}{10} \\ =66\frac{1}{2} \end{gathered}$$

Hence, the total saving of the day is $\text{Rs. 66}\frac{1}{2}\text{.}$
