26/12/24 – Three Course Meal

A man goes for a three-course meal and finishes with a coffee

  • The coffee cost half the price of the starter
  • The sweet cost the same as the starter plus the coffee
  • The main course cost twice the amount of the sweet
  • The total cost of the meal was £25.20

How much did the main course cost?

  • Show Answer

£12.60
If c = coffee, s = starter, m = main, d = dessert
t = 2c (clue 1), d = t + c (clue 2) so d = 3c, m = 6c (clue 3). Therefore, 2c + 3c + 6c + c = £25.20. 11c = £25.20. c = £2.10. m = £12.60.
