Example 2:Ramesh went to a cafeteria with his friends and asked for Menu. Given below is the menu of the cafeteria

Items | Price |
---|---|

Burger | Rs 75 each |

Pizza | Rs 350 each |

French Fries | Rs 90 |

Ice cream | Rs 70 per scoop |

Answer the following questions:

- If they ordered two burgers, five French fries, and five scoops of ice creams, then find the total amount they paid.
- If they divided the total amount among the five friends. Find the share of each friend.
- If they gave Rs 1000 then, calculate the amount they will get back.

Solution:

- The cost of one burger = Rs 75

The cost of two burgers = Rs 75 Ă— 2 = Rs 150

The cost of one packet of French fries = Rs 90

The cost of five packets of French fries = Rs 90 Ă— 5 = Rs 450

The cost of one scoop of ice cream = Rs 70

The cost of five scoops of ice cream = Rs 70 Ă— 5 = Rs 350

The total cost = Rs 150 + Rs 450 + Rs 350 = Rs 950 - Total cost = Rs 950
Number of students = 5

Share of each = Rs 950 Ă· 5

Amount each friend should give = Rs 190

- Amount given to the shopkeeper = Rs 1000
Total cost = Rs 950

Amount the shopkeeper will return = Rs 1000 â€“ Rs 950 = Rs 50
