Question

A 3-star hotel in Delhi charges 10% sales tax on the price of the food taken. Mr Saxena
and his family had food for 685. Find the total money he had to pay.​

Answer 1

Answer:

The sales tax charged by the hotel on the price of the food taken is 10%. The price for food taken by Mr. Suri and his family is Rs. 685. Now we will calculate the sales tax charged by the hotel for the food purchased by Mr. Suri and his family. To calculate that, we will use the following formula,

S=

10

100

×x, where x is the price of the food taken and S is the sales tax charged on x.

Substituting x=685 in the above equation, we get the following

S=

10

100

×685.

Simplifying the above equation, we get

S=

685

10

=68.5

Now, to calculate the total amount that had to be paid, we add the sales tax to the price of the food taken. Let the total amount to be paid be p Rs. Therefore,

p=x+S

Substituting the values of S and x, we get

p=685+68.5 =753.5
