Question

there are 100students in a class . in an examination, 77 students passed mathematics , 73 students passed English and 64students passed both how mny students failed in both subjects?​

Answer 1

Answer:

14

Step-by-step explanation:

both subjects =  $\frac{64}{100\\}$

English only = $\frac{73}{100} - \frac{64}{100}$ = $\frac{9}{100}$

Maths only = $\frac{77}{100} - \frac{64}{100} = \frac{13}{100}$

passed stdnts = 64+9+13=86

failed stdnts = 100-86=14
