a) 11.73 pounds
b) 12 pounds
c) 13.80 pounds
d) 14 pounds

  If average price per person=x

• Let the net price excluding the gratuity of service = x pounds
  Then, total price including 15% gratuity of service = x×(100+15100) = 1.15 x pounds
  So, 1.15 x = 207 pounds
  ⇒ x = 207 / 1.15 = 180 pounds
  Net price of lunch for each person = 180 / 15 = 12 pounds

• ans : 11.73 pounds
  
  first find for 1 person with gratuity :207/15 =13.8
  and without gratuity is : (85/100)13.8 = 11.730
