10. Determine how much lesser/ greater

In a college there are 4802 students. Each student has to contribute \(₹\)75 for annual day ceremony. A teacher tried to find the total amount to be collected. Instead of \(₹\)75, she multiplied by \(₹\)57. By how much was her answer lesser than the correct answer? 36015027371486436.

 

[Note: Think if there is any other possible way instead of finding the product for both case and subtracting it.]
