∴At the beginning of the game Sparrow had = (70+12)=82 coins

Step-by-step explanation:

Given , three pirates named Ahab, Sparrow and Davy play a game.

Let at the end of the game Ahab, Sparrow and Davy  have 4x, 5x,and 6x coins respectively.

Since,Ahab has won 5 coins and Davy has won 7 coins.This(7+5)=12 coins was belonged to Sparrow.
