Question

A petrol dealer sells on an average $360$ liters petrol daily. He claim to be selling at cost price.His machine thought is designed in such a way that each time petrol is delivered, $1/5^{th}$ is left over in the hose.What is his gain and total daily gain if 1 liter petrol costs Rs.63.50 ?

• A. $25\%,5667/-$
• B. $18\%,3112/-$
• C. $22\%,5435/-$
• D. $25\%,4572/-$

Answer 1

The correct option is D $25\%,4572/-$

He told that he sells 360 litres on avg but he does ${\frac{4}{5}}^{th}$ actually he should get for that;

$\frac{360\times 4}{5}\times 63.50=288\times 63.5=Rs.18288$

But he gets a profit of $\frac{360\times 1}{5}\times 63.50=Rs.4572$

that is $\frac{4572}{18288}\times 100$%$=25$
