Bunuel Can you explain the solution ?
TIA
At a particular school, 60 male students play sports. How many male students attend the school?
let male = m and female = f
we require to know male students who do not play game to find m...Lets see the statements--
(1) At the school, 3/4 of the female students play sports.so \(\frac{3}{4} f\)play sports and 60 male students play sports..
so tOTAL who play games = 3/4 f + 60Nothing about male students who do not play game
Insuff
(2) At the school, 1/4 of the students do not play sports.now we know 3/4 of total students play game..But we do not know the ratio of f:m..
Insuff
Combined--we know ONLY 3/4 of Total play games and ALSO from (1) 3/4 of 'f' play game
\(\frac{3}{4} (T) = \frac{3}{4} (f+m) = \frac{3}{4} m + \frac{3}{4} f\)...
also from (1) this is equal to \(\frac{3}{4} f + 60\)..
so \(\frac{3}{4} m + \frac{3}{4} f = \frac{3}{4} f + 60\).
OR 3/4 m = 60 or m= 60*4/3=80
