Answer 1

Answer:

155

Step-by-step explanation:

Let number of failed students  = x  

number of passed students  = 4 x

total students  = x + 4 x = 5 x

If there had been 35 fewer students appeared and 9 more had failed,

total students  = 5 x − 35

number of failed students  = x + 9

passed students  = ( 5 x − 35 ) −( x + 9 ) = 4x − 44

( 4 x − 44 ) : ( x + 9) = 2 : 1

2 ( x + 9 ) = 4 x − 44

2 x + 18 = 4 x − 44

2 x = 62

x = 31

total students was  5 x = 5 X 31 =155
