Knowing that the team lost 30 % of their matches, it has won 70 % of their matches

Total matches = 21 / (70/ 100) = 30

Hence number of matches that the team lost = 30 x 30/100 = 9

since percentage of matches lost =30%
thus percentage of matches won = 70%

Given team won 21 matches.
so, let x be the total number of matches
21= (70*x)/100
x=30
number of lost matches = 30-21 = 9

A. 70
B. 30
C. 9
D. 7
E. 5

We see that they won 70% of their matches, and if we let n = the total number of matches played, we can create the equation:

0.7n = 21

n = 30

Thus, the team lost 30 x 0.3 = 9 matches.

Answer: C

Dear Expert Bunuel , How can we assume that the rest 70% represents won matches? There can be draws/ties as well right? I think my thinking along the GMAT way is wrong but pls explain what to assume and what not to according to gmat. Nothing is mentioned in qstn stem that there were only wins and losses and no ties. So how can we assume that there are only wins and losses, that is , the rest 70% represents matches won, which is , 21?

So how can we assume that there are only wins and losses, that is , the rest 70% represents matches won, which is , 21?

Please note -

lost 30% of their matches = won 70% match { Total Matches = Matches won + Matches Lost }

We know , 100 = 30 ( Lost ) + 70 ( Won)

Given
Quote:
During one season, a tennis team won 21 matches
Thus, won 70% of total match = 21

So, Total no of matches is \(\frac{21*100}{70}= 30\)

Thus, total matches lost is 30% of 30 = 9

Hope this helps...

But how are we assuming that the rest 70% represents wins only? The rest 70% can be wins as well as ties/draws right ? Total matches = matches won + matches lost + matches tied?
