In an 8 round tennis tournament Petru wins 3, draws 1 and loses the rest. What is his ratio of wins: lose : draw?
A) 3 : 1 : 4
B) 4 : 3 : 1
C) 3 : 4 : 1
D) 4 : 1 : 3

3:4:1

Step-by-step explanation:

As, he wins 3

And draws 1

And the reat he loses

So the ones he loses = 4

As, 3 he won + 1 he draws = 4

So total are 8 rounds = 8 - 4 = 4

So 4 rounds he loses

So wins = 3

Loses = 4

Draws = 1

So wins :lose : draws

= (B) 3 : 4 : 1
